10. Bangs Laboratories

These companies manufacture or supply PMMA microspheres for one or more of the following applications:

• Optical diffusion;

• Light-scattering films;

• Anti-glare coatings;

• Industrial coatings;

• Paints and inks;

• Polymer modification;

• Composite materials;

• Spacer applications;

• Particle-size calibration;

• Microfluidics;

• Custom particle development.

SANYU is ranked second and is the only China-based manufacturer included in this guide.

This ranking differs from several generic PMMA market reports.

Some current market reports still list Phosphorex among leading PMMA microsphere companies. However, Phosphorex currently states that its standard PMMA product line has been discontinued and that PMMA is now available only through custom quantity orders subject to an agreed minimum. For that reason, it is not included in the main Top 10 ranking.

“Serving Europe” does not mean that every company manufactures PMMA particles inside the European Union.

Some manufacturers are located in Europe, while others supply European customers through:

• European subsidiaries;

• Regional distributors;

• International laboratory distributors;

• Direct international shipment;

• OEM or custom manufacturing agreements.

For European buyers, supplier selection in 2026 also requires consideration of the EU restriction on synthetic polymer microparticles.

PMMA particles that meet the regulatory definition of synthetic polymer microparticles may be subject to REACH Entry 78 restrictions, information requirements, transitional periods, derogations or reporting obligations depending on how they are supplied and used.

The final supplier should therefore be selected on both technical and regulatory criteria.

What “Serving Europe” Means in This Ranking

This guide covers suppliers whose PMMA microspheres may be relevant to customers across major European markets including:

• Germany;

• France;

• Italy;

• Spain;

• Netherlands;

• Belgium;

• Austria;

• Poland;

• Czech Republic;

• Scandinavia;

• Ireland;

• Other EU and European markets.

For regulatory discussion, this article primarily focuses on the European Union.

The United Kingdom, Switzerland and certain other European markets operate under separate chemical or product regulatory systems, so companies supplying those countries should verify the applicable local rules separately.

The manufacturers in this guide may serve European:

• Coating manufacturers;

• Paint and ink companies;

• Polymer processors;

• Optical-material companies;

• Electronics manufacturers;

• Cosmetic formulators;

• Biotechnology companies;

• Diagnostic developers;

• Medical research laboratories;

• Universities;

• Particle-analysis laboratories;

• OEM material developers.

A company’s inclusion does not guarantee that every PMMA product:

• Is stocked in Europe;

• Is compliant with every European end-use regulation;

• Can be used in cosmetics;

• Can be used in medical devices;

• Is exempt from REACH microplastic restrictions;

• Is available at industrial scale.

European buyers should independently confirm the regulatory status of the exact PMMA grade and intended use.

What Are PMMA Microspheres?

PMMA microspheres are spherical particles manufactured from poly(methyl methacrylate), usually abbreviated PMMA.

Common commercial descriptions include:

• PMMA microspheres;

• PMMA particles;

• Acrylic microspheres;

• Acrylic beads;

• PMMA microbeads;

• PMMA spherical powder;

• Polymethyl methacrylate spheres.

PMMA is an optically transparent acrylic polymer with properties that make it useful for applications requiring controlled:

• Particle size;

• Density;

• Optical scattering;

• Mechanical behavior;

• Surface chemistry;

• Polymer compatibility.

PMMA particles can range from nanoscale colloids to millimeter-scale spheres.

For example, German manufacturer microParticles GmbH currently offers monodisperse PMMA from 100 nm to 200 µm, while Cospheric lists PMMA acrylic spheres from approximately 1 µm to 3.5 mm.

These products serve very different applications and should not be treated as interchangeable.

Typical PMMA Microsphere Applications

Common PMMA microsphere applications include:

• Light-diffusion films;

• LED diffusers;

• Optical coatings;

• Anti-glare materials;

• Paint additives;

• Matting agents;

• Texture modifiers;

• Polymer fillers;

• Composite materials;

• Adhesives;

• Spacers;

• Microfluidic research;

• Biomedical engineering;

• Particle standards;

• Imaging research;

• Cosmetics;

• Personal-care powders.

The best manufacturer therefore depends heavily on the intended application.

PMMA Microspheres vs Polystyrene and Silica Microspheres

PMMA, polystyrene and silica microspheres can sometimes serve similar functions, but their material properties differ substantially.

PMMA vs Polystyrene Microspheres

PMMA generally has a density of approximately 1.19 g/cm³ and refractive index around 1.49, while typical polystyrene microspheres are less dense and have a higher refractive index.

Bangs Laboratories summarizes representative bulk-material values of approximately:

• PMMA density: 1.19 g/cm³;

• PMMA refractive index: 1.49;

• Polystyrene density: 1.05 g/cm³;

• Polystyrene refractive index: 1.59.

These differences affect:

• Sedimentation;

• Optical scattering;

• Centrifugation;

• Calibration;

• Composite behavior.

Polysciences also notes that PMMA is less hydrophobic than polystyrene and may show reduced nonspecific protein or peptide binding in some applications.

PMMA vs Silica Microspheres

Silica is substantially denser than PMMA and has a different inorganic surface chemistry.

Silica is often preferred when applications require:

• Silanol surface chemistry;

• High rigidity;

• High temperature stability;

• Inorganic particle behavior.

PMMA may be preferred when users require:

• Lower density;

• Acrylic polymer compatibility;

• Optical clarity;

• Polymer processability;

• Controlled crosslinking;

• Organic surface modification.

The correct matrix depends on the final application rather than simply price or nominal particle size.

Broad-distribution PMMA products are less tightly size-controlled.

They may be suitable for:

• General coatings;

• Industrial fillers;

• Polymer modification;

• Texture development;

• Cost-sensitive applications.

The required distribution should always be specified using parameters such as D10, D50 and D90 rather than simply requesting a nominal diameter.

Request:

• Mean diameter;

• Median diameter;

• Standard deviation;

• CV;

• D10;

• D50;

• D90.

For precision applications, CV may be more important than nominal diameter.

microParticles, for example, specifies CV below 5% for its monodisperse PMMA platform.

3. Sphericity

Particle shape affects:

• Flowability;

• Optical scattering;

• coating texture;

• packing;

• spacer performance;

• calibration.

Ask for:

• SEM images;

• aspect ratio;

• circularity;

• percentage spherical.

4. PMMA Density

Representative PMMA density is approximately 1.19 g/cm³.

Density affects:

• Sedimentation;

• centrifugation;

• suspension stability;

• composite weight;

• particle transport.

5. Refractive Index

Representative PMMA refractive index is approximately 1.48–1.49 in the visible region, depending on wavelength and material formulation.

Optical users should request the manufacturer’s actual measurement conditions.

6. Crosslinking

Determine whether the PMMA is:

• Non-crosslinked;

• Lightly crosslinked;

• Highly crosslinked.

Crosslinking can affect:

• Solvent resistance;

• swelling;

• mechanical stiffness;

• dimensional stability;

• processing.

7. Porosity

For porous particles, ask for:

• Pore volume;

• pore size;

• specific surface area;

• oil absorption;

• bulk density.

8. Surface Chemistry

Depending on the application, useful options include:

• Plain PMMA;

• COOH-PMMA;

• NH2-PMMA;

• fluorescent PMMA;

• custom-functionalized PMMA.

9. Residual Monomer

For sensitive applications, request the residual methyl methacrylate specification.

This can be especially important for:

• Cosmetics;

• Biomedical research;

• specialty electronics;

• high-purity coatings.

10. Moisture

For dry PMMA powder, excessive moisture may affect:

• Flowability;

How to Choose PMMA Microspheres for Optical Applications

PMMA microspheres are frequently used to modify light scattering.

Potential applications include:

• Light-diffusion films;

• LED covers;

• anti-glare coatings;

• optical sheets;

• display materials;

• lighting components.

Important specifications include:

• Diameter;

• size distribution;

• refractive index;

• transparency;

• sphericity;

• surface roughness;

• dispersion.

Sekisui Kasei specifically develops TECHPOLYMER for light-diffusion applications and states that particle diameter, refractive properties and solvent resistance can be adjusted.

Haze vs Transmission

Increasing light scattering may increase haze but can reduce total light transmission.

The correct PMMA particle therefore depends on:

• Polymer matrix;

• wavelength;

• particle loading;

• film thickness;

• particle diameter;

• refractive-index difference.

Optical performance should always be tested in the actual host polymer or coating.

How to Choose PMMA Microspheres for Coatings

PMMA particles can modify:

• Gloss;

• matting;

• surface texture;

• scratch behavior;

• optical appearance;

• coating feel.

Important parameters include:

• Particle size;

• distribution;

• crosslinking;

• solvent resistance;

• surface compatibility;

• dispersion quality.

Sekisui Kasei positions TECHPOLYMER as a coating additive for gloss reduction, texture effects and abrasion resistance.

Matsumoto’s crosslinked PMMA grades are particularly relevant when solvent resistance is needed.

PMMA and Solid-Matrix Applications Under EU REACH

European coating developers should not assume that all PMMA particle uses are automatically prohibited.

The EU microplastics restriction contains derogations for some synthetic polymer microparticles that are permanently incorporated into a solid matrix during intended end use.

The Commission specifically uses certain paints and inks as examples where microplastics may become permanently incorporated into a solid matrix.

However, compliance may still involve:

• Conditions of use;

• release-prevention instructions;

• supplier information requirements;

• reporting requirements.

The specific supply chain should therefore be reviewed rather than relying on a simple “allowed” or “banned” statement.

How to Choose PMMA Microspheres for Cosmetics

PMMA has historically been used in cosmetics to provide:

• Slip;

• silky texture;

• soft-focus effects;

• mattifying behavior;

• oil absorption;

• reduced tack.

Relevant manufacturers include:

• Sekisui Kasei;

• Matsumoto;

• Sunjin Beauty Science;

• Kolon Industries.

However, cosmetics are one of the areas most affected by the EU microplastics restriction.

EU Cosmetic Transition Periods

Under Regulation (EU) 2023/2055, transition periods apply to different cosmetic categories containing synthetic polymer microparticles.

The current Commission guidance identifies deadlines including:

• Rinse-off cosmetics: 17 October 2027;

• Leave-on cosmetics: 17 October 2029;

• Lip, nail and make-up products: 17 October 2035.

From 17 October 2031 through the end of the applicable transition period, specified make-up, lip and nail products containing microplastics will also require an indication that the product contains microplastics.

European cosmetic formulators evaluating PMMA in 2026 should therefore consider not only current legality but also the commercial lifetime of the formulation.

A product launched in 2026 may still be on the market when a transition period expires.

How to Choose PMMA Microspheres for Biomedical Research and Calibration

Precision PMMA particles are useful in:

• Microfluidics;

• Biomedical imaging;

• Flow studies;

• calibration;

• instrument validation;

• diagnostic research.

Important parameters include:

• Diameter;

• CV;

• density;

• refractive index;

• autofluorescence;

• surface functionality;

• suspension stability.

microParticles GmbH is especially relevant because it combines a 100 nm–200 µm range, CV below 5%, functionalized surfaces and fluorescent PMMA.

Polysciences may be useful where submicron aqueous PMMA and reduced hydrophobicity are desired.

Dry PMMA Powder vs Aqueous PMMA Suspension

Dry Powder

Dry PMMA is generally more suitable for:

• Polymer compounding;

• coatings;

• paints;

• optical materials;

• composite fillers.

Advantages include:

• High solids;

• lower water shipping weight;

• flexible formulation concentration.

Potential challenges include:

• Dust;

• agglomeration;

• dispersion requirements;

• microplastic release control during handling.

Aqueous Suspension

Aqueous PMMA may be preferred for:

• Laboratory experiments;

• calibration;

• biomedical research;

• microfluidics;

• particle analysis.

Advantages include:

• Easier pipetting;

• reduced airborne powder;

• ready-to-use dispersion.

Potential challenges include:

• Freeze sensitivity;

• shipping weight;

• preservative;

• surfactant interference;

• sedimentation.

The application should determine the preferred form.

EU REACH Microplastics Regulation and PMMA Microspheres

Why This Matters in 2026

Commission Regulation (EU) 2023/2055 amended REACH Annex XVII to restrict synthetic polymer microparticles on their own or intentionally added to mixtures.

The restriction began applying on 17 October 2023.

PMMA particles can fall within the synthetic polymer microparticle definition when the relevant criteria are met.

That does not mean every PMMA microsphere application is prohibited.

The regulation contains:

• Exclusions;

• derogations;

• transitional periods;

• information obligations;

• emission-reporting requirements.

Particle Size Matters

The restriction broadly addresses certain solid synthetic polymer particles below 5 mm.

Because most commercial PMMA microspheres are well below 5 mm, European buyers should assume that regulatory assessment may be necessary unless they have clear evidence that the material or use falls outside the definition or within an applicable exception.

Industrial Uses

Some industrial uses may continue under derogations, including uses at industrial sites and certain applications where particles are permanently incorporated into a solid matrix.

However, suppliers and users can still have information and reporting obligations.

Since 17 October 2025, suppliers of synthetic polymer microparticles for certain industrial-site uses must provide information including instructions on preventing releases and information identifying the polymer and its concentration.

Reporting Began in 2026

ECHA states that the first microplastic annual reporting requirements began in 2026.

For manufacturers and industrial downstream users of synthetic polymer microparticles in pellet, flake and powder form used as feedstock for plastic manufacturing at industrial sites, estimated 2025 emissions had to be reported by 31 May 2026.

Other industrial users and certain suppliers enter the reporting system from 2027.

This makes environmental release data increasingly relevant when selecting PMMA suppliers.

What European Buyers Should Request From PMMA Suppliers

For products potentially subject to Entry 78, request:

• Polymer identity;

• Particle-size information;

• concentration;

• solubility information where relevant;

• degradability information where relevant;

• applicable REACH classification;

• intended-use limitations;

• handling instructions;

• disposal instructions;

• emission-prevention guidance;

• supplier reporting responsibilities.

Do Not Assume “REACH Compliant” Means Every Use Is Allowed

A generic statement such as “REACH compliant” is not sufficient.

Compliance depends on:

• Particle properties;

• concentration;

• intended use;

• user type;

• application;

• whether the particles remain particles after use;

• whether they are permanently incorporated into a solid matrix;

• applicable transitional period.

Product-specific review is advisable for commercial European projects.

Can PMMA microspheres still be sold in Europe in 2026?

It depends on the exact particle and intended use.

The EU has restricted synthetic polymer microparticles through REACH, but there are exemptions, derogations and transitional periods for specific uses.

A general “PMMA is banned” statement is therefore inaccurate.

Likewise, a general “all PMMA microspheres are allowed” statement is inaccurate.

The specific supply chain and end use must be evaluated.

Are PMMA microspheres considered microplastics under EU REACH?

They can be.

PMMA microspheres meeting the relevant synthetic polymer microparticle definition may fall within REACH Entry 78.

Particle properties and applicable exclusions must be reviewed for the exact grade.

Are PMMA particles permanently embedded in coatings automatically prohibited?

Not necessarily.

The EU restriction contains derogations for some uses where particles are permanently incorporated into a solid matrix during intended use.

Certain paints and inks are specifically used in Commission guidance as examples of this situation.

Did new reporting requirements begin in 2026?

Yes.

ECHA’s first annual microplastics emission reporting deadline was 31 May 2026 for specified manufacturers and industrial users of relevant feedstock particles, covering 2025 emissions.

Can PMMA still be used in cosmetics in Europe?

Some cosmetic categories remain within transitional periods in 2026.

Current Commission guidance identifies transition deadlines in 2027, 2029 and 2035 depending on cosmetic category.

Companies developing new cosmetic formulations should plan around the end date applicable to their product type.

Is Phosphorex still a standard PMMA microsphere supplier?

No standard PMMA line is currently offered.

Phosphorex states that its standard PMMA product line has been discontinued, although custom quantity orders may still be accepted subject to a minimum.

That is why Phosphorex is not included in this Top 10 ranking.

What is the typical density of PMMA?

A representative PMMA density is approximately 1.19 g/cm³.

Always use the supplier’s actual value for precision calculations.

What is the refractive index of PMMA?

Representative visible-light values are approximately 1.48–1.49 depending on formulation and wavelength.

Can PMMA products from different manufacturers be used interchangeably?

Not automatically.

Two products both described as “10 µm PMMA microspheres” may differ in:

• CV;

• D10/D50/D90;

• crosslinking;

• surface chemistry;

• sphericity;

• residual monomer;

• additives;

• moisture;

• suspension formulation.

Supplier changes should be validated.

What documents should European PMMA buyers request?

At minimum, request:

• Certificate of Analysis;

• Safety Data Sheet;

• Technical Data Sheet;

• Particle-size report;

• Size-distribution data;

• Polymer composition;

• Crosslinking information;

• Residual monomer specification where relevant;

• Storage conditions;

• Shelf life;

• REACH information;

• Microplastics Entry 78 assessment;

• Change-notification policy.

How many suppliers should be evaluated?

For commercial projects, evaluating at least two or three technically suitable suppliers is recommended.

This reduces technical and supply-chain risk.

Should price be the main supplier-selection criterion?

No.

A lower particle price can be outweighed by:

• Poor size consistency;

• agglomeration;

• optical variation;

• coating defects;

• formulation instability;

• regulatory non-compliance;

• long import lead times;

• supplier changes;

• revalidation costs.

Final Recommendations

Choose microParticles GmbH when the project requires European manufacturing, extremely precise monodisperse PMMA, functionalized surfaces, fluorescence or particle sizes from approximately 100 nm to 200 µm.

Choose SANYU when the project requires customized PMMA particle sizes, conventional or crosslinked PMMA, dry and aqueous formats, flexible packaging or factory-direct OEM and bulk supply.

Choose Cospheric when the project requires an exceptionally broad PMMA size range, including large acrylic spheres extending into the millimeter range.

Choose Matsumoto Yushi-Seiyaku for crosslinked, non-crosslinked, hollow or modified-shape PMMA particles used in coatings, fillers and specialty formulations.

Choose Polysciences when the project requires submicron monodisperse PMMA for biomedical, diagnostic or laboratory research.

Choose Sekisui Kasei when the application involves light diffusion, optical films, industrial coatings, porous PMMA or cosmetic sensory modification.

Choose Magsphere when the project requires aqueous PMMA latex across multiple particle sizes or custom particle-development support.

Choose Kolon Industries for DIASPHERE PMMA used in optical materials, displays, coatings, polymer modification and cosmetics.

Choose Sunjin Beauty Science for cosmetic PMMA and sensory powder applications, while carefully considering EU microplastic transition deadlines for any new European formulation.

Choose Bangs Laboratories when the project requires solid non-porous PMMA, diagnostic research support, particle characterization or customized polymer microspheres.

For European customers in 2026, the final supplier should not be selected only by nominal particle size, brand recognition or price.

A stronger procurement process is to:

1. Define the PMMA application;

2. Specify particle diameter and distribution;

3. Define crosslinking, porosity and surface chemistry;

4. Select dry powder or aqueous suspension;

5. Determine whether the particle falls within EU REACH Entry 78;

6. Identify the applicable derogation, exemption or transitional period;

7. Obtain samples from multiple manufacturers;

8. Evaluate the particles in the final formulation;

9. Compare multiple production lots;

10. Review REACH information and emission-control obligations;

11. Confirm commercial-scale supply;

12. Establish formal supplier specifications and advance change control.

This approach gives European optical-material, coating, cosmetic, biotechnology, diagnostic and research companies a more reliable foundation for selecting PMMA microspheres in 2026.
