30um Spacer PS Microspheres PAPS30UM

30um Spacer PS Microspheres PAPS30UM

SHBC PAPS30UM are precision 30 μm polystyrene microspheres developed for gap control, bond-line thickness control and component spacing.

The uniform spherical particles form physical support points between substrates or bonded components. PAPS30UM can be evaluated for adhesives, electronic packaging, optical components, display materials, smart glass and precision assembly.

Product Specifications

Batch-specific particle size distribution, solid content, supply form, packaging and storage information are available in the product specification or Certificate of Analysis.

Key Advantages

Controlled 30 μm Spacing

The nominal particle diameter helps create a defined gap between bonded surfaces or functional layers.

Uniform Spherical Morphology

Regular spherical particles provide stable support points and help reduce local thickness variation.

Controlled Particle Size Distribution

Consistent particle sizing supports repeatable gap formation and assembly performance.

Smooth Particle Surface

The smooth surface supports dispersion in compatible adhesives, sealants, coatings and carrier systems.

Stable Polymer Structure

The polystyrene matrix provides physical support during normal bonding and assembly processes.

Scalable Supply

SHBC supports sample evaluation, pilot orders, customized specifications and bulk production.

Main Applications

Adhesive Bond-Line Control

PAPS30UM can be mixed into compatible adhesives and sealants to help maintain an approximately 30 μm bonding gap.

Semiconductor Packaging

Suitable for evaluating adhesive thickness control between chips, substrates and packaging components.

Electronic Component Assembly

Used to maintain controlled spacing between circuit boards, housings, sensors and other components.

Optical Component Bonding

Can be added to optical adhesives to support uniform spacing between lenses, glass, films or other optical parts.

Smart Glass and Display Materials

Suitable for structures requiring controlled separation between glass substrates or functional layers.

Coating Thickness Control

Can be evaluated as a physical thickness-control material in compatible coatings and polymer systems.

How 30um Spacer Microspheres Work

PAPS30UM microspheres are dispersed in an adhesive, coating or compatible carrier.

During assembly, the particles form physical support points between two surfaces. Their nominal diameter helps limit compression and define the final separation distance.

The actual gap may vary according to particle size distribution, particle loading, assembly pressure and material properties.

Benefits for Manufacturers

PAPS30UM helps support:

• Controlled 30 μm spacing

• Uniform bond-line thickness

• Consistent support-point distribution

• Reduced local gap variation

• Repeatable bonding processes

• Improved component alignment

• Customized formulation development

• Sample-to-bulk scale-up

Adhesive Application Guidance

Disperse the microspheres evenly in the adhesive before dispensing or coating.

Important factors include:

• Adhesive compatibility

• Particle concentration

• Adhesive viscosity

• Bonding area

• Dispensing method

• Assembly pressure

• Required support-point density

• Target final thickness

Excessive particle loading may affect adhesive flow and dispensing. Insufficient loading may not provide enough support points across the bonding area.

Laboratory validation is recommended before production use.

Dispersion Recommendations

Use gentle mechanical mixing to distribute the particles evenly.

Controlled ultrasonic treatment may be used when compatible with the adhesive or carrier system. Avoid excessive mixing conditions that may introduce air bubbles or affect the formulation.

Customers should evaluate:

• Particle settling

• Particle aggregation

• Dispensing stability

• Bond strength

• Final bond-line thickness

• Long-term material compatibility
