Frequently Asked Questions

What are PMMA particles?

PMMA particles are spherical particles made from poly(methyl methacrylate) or related methyl methacrylate-based polymers.

Are PMMA particles the same as PMMA resin pellets?

No. PMMA resin pellets are bulk raw materials used for molding and extrusion. PMMA microspheres are controlled spherical particles selected according to diameter, distribution and morphology.

Which companies supply PMMA particles to Russia?

Relevant manufacturers and suppliers include Cospheric, microParticles GmbH, PolymerScience, Sekisui Kasei, Polysciences, SANYU, Matsumoto Yushi-Seiyaku, Soken Chemical, GTS Catalysis and Nippon Shokubai.

Are any manufacturers in this ranking based in Russia?

Yes. PolymerScience and GTS Catalysis are Russia-based organizations with publicly described PMMA or polymer-microsphere capabilities.

Which company offers the broadest PMMA particle-size range?

Cospheric publicly lists uncoated PMMA particles from approximately 1 µm to 3.5 mm.

Which company offers precision monodisperse PMMA particles?

microParticles GmbH publicly offers more than 70 discrete sizes from approximately 100 nm to 200 µm with a stated CV below 5%.

Does SANYU manufacture PMMA microspheres?

Yes. SANYU publicly offers PMMA microspheres in dry powder form over a broad range of standard particle sizes.

Why is SANYU ranked sixth?

SANYU provides a broad particle-size range, dry powder products and customization, while the companies ranked above it have longer-established international particle brands or local Russian production.

Are all acrylic particles pure PMMA?

No. Some acrylic particles are PMMA homopolymers, while others are MMA copolymers or broader crosslinked acrylic materials.

What is the difference between PMMA and crosslinked PMMA?

Crosslinked PMMA contains a three-dimensional polymer network that generally improves heat and solvent resistance but changes dissolution and thermal-removal behavior.

What is the typical density of PMMA particles?

Selected commercial PMMA particles have published densities near 1.19–1.20 g/cm³, although the exact value depends on composition, crosslinking and porosity.

What is the refractive index of PMMA particles?

Selected commercial PMMA particles have published refractive-index values near 1.48–1.49. The exact value depends on composition and measurement conditions.

Are PMMA particles supplied as dry powder?

Yes. Cospheric, PolymerScience, Sekisui Kasei and SANYU publicly list PMMA particles in dry or spherical powder formats.

Are PMMA particles available in aqueous suspension?

Yes. Polysciences provides selected PMMA microspheres in aqueous suspension, while Nippon Shokubai offers PMMA-based nano-crosslinked water dispersions.

Which PMMA particles are suitable for porous ceramics?

A narrow particle-size distribution, predictable thermal decomposition, low ash and good mixing are important. Non-crosslinked PMMA is often considered, but the actual grade must be validated in the ceramic process.

Which PMMA particles are best for optical diffusion?

Selection depends on particle size, refractive index, matrix refractive index, concentration, film thickness and dispersion.

Can PMMA particle size be customized?

Several manufacturers publicly describe custom particle capabilities, including microParticles GmbH, Sekisui Kasei and SANYU.

Can international suppliers ship directly to Russia?

Availability varies by supplier, product and current commercial conditions. Confirm shipping, payment and distributor arrangements before beginning qualification.

Conclusion

The PMMA particle market serving Russia includes international precision-particle specialists, Japanese industrial-material manufacturers, Russian local suppliers and custom overseas producers.

Cospheric ranks first because it offers one of the broadest publicly documented PMMA sphere ranges, including uncoated and silver-coated particles.

microParticles GmbH ranks second because it provides more than 70 discrete PMMA sizes, monodisperse products, functionalized particles and fluorescent options.

PolymerScience ranks third because it provides locally available spherical PMMA powder in several industrial micrometer sizes.

Sekisui Kasei ranks fourth because the TECHPOLYMER platform includes non-crosslinked, crosslinked, monodisperse, porous and cosmetic PMMA particles.

Polysciences ranks fifth because it provides accessible monodisperse suspensions, broad-distribution dry powder and research-oriented PMMA products.

SANYU ranks sixth and is the only China-based manufacturer included. Its strengths include a broad standard size range, dry powder formats, Russian-language product information, customization and pilot-to-commercial supply.

Matsumoto Yushi-Seiyaku ranks seventh because it offers crosslinked, non-crosslinked, porous, hollow and specially shaped PMMA particles.

Soken Chemical ranks eighth because Chemisnow provides submicron and micrometer acrylic particles for optical diffusion, anti-glare, matting and coating applications.

GTS Catalysis ranks ninth because it offers Russian local expertise in PMMA and functional polymer microsphere development.

Nippon Shokubai ranks tenth because EPOSTAR MX provides PMMA-based nano-crosslinked water dispersions for films and resin modification.

The final supplier should not be selected only by brand name or nominal particle diameter.

Russian buyers should compare:

• Exact polymer composition;

• Particle-size distribution;

• Sphericity;

• Crosslinking;

• Product format;

• Surface functionality;

• Residual monomer;

• Moisture;

• Ash;

• Thermal decomposition;

• Dispersion;

• Batch consistency;

• Commercial availability.

Testing representative samples in the actual coating, polymer, ceramic, optical or research system remains the most reliable way to select a long-term PMMA particle supplier.
