8um Spacer PS Microspheres PAPS8UM

8um Spacer PS Microspheres PAPS8UM

SHBC PAPS8UM are uniform 8 μm polystyrene microspheres developed for precision spacing and thickness control.

The spherical particles form physical support points between substrates, films or bonded components. They can be evaluated for LCD, PDLC, smart glass, optical materials, adhesive bonding and electronic assembly.

Product Specifications

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

Key Advantages

Controlled 8 μm Spacing

The nominal particle diameter helps maintain a defined separation between two surfaces or functional layers.

Uniform Spherical Morphology

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

Controlled Particle Size Distribution

Uniform particle sizing supports repeatable gap control and stable processing.

Smooth Particle Surface

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

Stable Polystyrene Structure

The PS matrix maintains particle integrity during normal dispersion, coating and assembly processes.

Consistent Batch Supply

SHBC supports sample testing, pilot-scale orders and bulk production for industrial material projects.

Main Applications

LCD Cell Gap Control

Used between LCD substrates to help maintain a consistent liquid crystal layer thickness.

PDLC Films

Suitable for polymer-dispersed liquid crystal films requiring controlled spacing between functional layers.

Smart Glass

Can be evaluated in switchable and light-control glass structures requiring uniform layer separation.

Adhesive Gap Control

Added to compatible adhesives or sealants to help maintain a defined bond-line thickness.

Optical Films and Components

Used for coating thickness control, optical layer separation and precision material development.

Touch Panels and Sensors

Suitable for assemblies requiring micron-level separation between glass, films, sensors or electronic components.

Electronic Assembly

Can be evaluated for spacing between substrates, chips, housings and packaging materials.

How 8um Spacer Microspheres Work

PAPS8UM microspheres are dispersed in a compatible carrier or positioned between two substrates.

During assembly, the particles act as physical support points. Their nominal 8 μm diameter helps define the final gap and reduces direct contact between the two surfaces.

Benefits for Manufacturers

PAPS8UM helps support:

• Controlled 8 μm gap formation

• Uniform layer thickness

• Consistent spacer distribution

• Reduced direct substrate contact

• Repeatable assembly processes

• Compatibility with multiple material systems

• Customized specification development

• Sample-to-bulk scale-up

Dispersion and Use

Disperse the microspheres evenly before coating, spraying or mixing into an adhesive.

Important processing factors include:

• Carrier compatibility

• Microsphere concentration

• Material viscosity

• Dispersion time

• Ultrasonic conditions

• Coating or spraying method

• Assembly pressure

• Target spacer density

Gentle mixing or controlled ultrasonic dispersion may help reduce particle aggregation. Final processing conditions should be optimized for the customer’s formulation.

Adhesive Gap-Control Applications

When mixed into an adhesive, PAPS8UM provides physical support points during bonding.

The recommended particle concentration depends on:

• Bonding area

• Adhesive volume

• Dispensing method

• Required support-point density

• Assembly pressure

• Target bond-line thickness

Compatibility and process testing are recommended before production use.
