10um Spacer PS Microspheres PAPS10UM 10%

10um Spacer PS Microspheres PAPS10UM

SHBC PAPS10UM are precision 10 μm polystyrene microspheres developed for gap control, thickness control and micron-level spacing.

The uniform spherical particles provide stable support between substrates, films and bonded components. They are suitable for LCD, PDLC, smart glass, optical materials, adhesive bonding and electronic assembly.

Product Specifications

Particle size distribution, solid content, supply form and packaging are provided according to the final product specification and batch Certificate of Analysis.

Key Advantages

Precise 10 μm Gap Control

The controlled particle diameter helps maintain a defined 10 μm separation between two substrates or functional layers.

Uniform Spherical Morphology

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

Controlled Particle Size Distribution

Uniform particle sizing supports stable gap formation and repeatable manufacturing results.

Smooth Particle Surface

The smooth surface supports even distribution 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

Controlled production supports laboratory evaluation, pilot-scale orders and long-term bulk supply.

Main Applications

LCD Cell Gap Control

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

PDLC Films

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

Smart Glass

Can be evaluated in switchable glass and light-control 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 optical layer separation, coating thickness control and precision material development.

Touch Panels and Sensors

Suitable for assemblies requiring micron-level spacing between glass, films, sensors and electronic components.

Electronic Assembly

Can be evaluated for controlling the distance between substrates, chips, housings and packaging materials.

How 10um Spacer Microspheres Work

PAPS10UM microspheres are dispersed in a compatible carrier or positioned between two substrates.

During assembly, the particles act as physical support points. Their nominal 10 μm diameter helps define the final separation distance and reduces direct contact between the two surfaces.

Product Benefits

PAPS10UM helps support:

• Controlled 10 μm spacing

• Uniform layer thickness

• Consistent spacer distribution

• Reduced local gap variation

• Repeatable assembly processes

• Compatibility with multiple material systems

• Customized product development

• Sample-to-bulk scale-up

Dispersion and Use

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

Important processing factors include:

• Carrier compatibility

• Microsphere concentration

• Material viscosity

• Dispersion time

• Ultrasonic conditions

• Coating or spraying method

• Assembly pressure

• Required spacer density

Gentle mixing or controlled ultrasonic dispersion may help reduce particle aggregation. Final conditions should be optimized according to the customer’s formulation and process.

Adhesive Gap-Control Applications

When mixed into an adhesive, PAPS10UM provides physical support points during bonding.

The recommended microsphere concentration depends on:

• Bonding area

• Adhesive volume

• Dispensing method

• Required support-point density

• Assembly pressure

• Target bond-line thickness

Material compatibility and process validation are recommended before production use.
