3um Spacer PS Microspheres PAPS3UM

3um Spacer PS Microspheres PAPS3UM

SHBC PAPS3UM are precision-manufactured 3 μm polystyrene microspheres developed for micron-level spacing and gap control.

The uniform spherical particles help maintain a consistent distance between substrates, films, coatings and bonded components. They are suitable for LCD, PDLC, touch panels, optical materials and precision assembly applications.

Product Specifications

Particle size distribution, solid content, dispersion medium, packaging and storage information are provided according to the final product specification and batch Certificate of Analysis.

Key Product Advantages

Precise 3 μm Gap Control

The controlled particle diameter helps create a stable micron-level separation between two material surfaces.

Uniform Spherical Morphology

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

Narrow Particle Size Distribution

Controlled particle uniformity supports stable spacer performance and repeatable processing.

Smooth Particle Surface

The smooth surface helps the microspheres distribute more evenly in coatings, adhesives and functional material systems.

Stable Polystyrene Structure

The PS matrix provides reliable particle integrity during dispersion, coating and assembly processes.

Consistent Batch Quality

Controlled production supports repeatable particle size and performance for research, pilot-scale testing and industrial supply.

How 3um Spacer Microspheres Work

Spacer microspheres are distributed between two substrates or functional layers.

After assembly, the microspheres act as physical support points. Their diameter helps define the final gap thickness while preventing direct contact between the two surfaces.

A nominal diameter of 3 μm makes PAPS3UM suitable for thin-layer structures requiring controlled and repeatable spacing.

Main Applications

LCD Cell Gap Control

PAPS3UM can be used as spacer particles between LCD substrates to help maintain a uniform liquid crystal cell gap.

PDLC Films

Suitable for polymer-dispersed liquid crystal films requiring controlled thickness and stable layer separation.

Touch Panels and Sensors

Can be evaluated for touch-panel sealing, sensor structures and other devices requiring precise gap control.

Optical Films and Coatings

Used to control coating thickness, layer separation and surface structure in optical material development.

Precision Adhesive Bonding

Added to adhesives or sealing materials to help maintain a defined bond-line thickness.

Microelectronic Assembly

Suitable for micron-level spacing and structural support between electronic or microfabricated components.

LCD spacer particles are commonly used to control display cell gaps, while related precision spacer materials are also applied in touch panels, sensors and other thickness-control systems.

Benefits for Material Manufacturers

PAPS3UM helps manufacturers achieve:

• More uniform layer thickness

• Controlled 3 μm spacing

• Reduced surface-to-surface contact

• Consistent spacer distribution

• Improved process repeatability

• Compatibility with thin-film structures

• Scalable supply for production projects

Recommended Dispersion

Before use, disperse the microspheres uniformly in the selected carrier, adhesive, coating or solvent system.

Recommended evaluation factors include:

• Carrier compatibility

• Microsphere loading

• Dispersion time

• Ultrasonic treatment

• Material viscosity

• Target spacer density

• Coating or spraying method

For wet dispersion, customers should confirm the compatibility of the microspheres with their solvent and production process. Competitor spacer suppliers commonly recommend controlled solvent dispersion and ultrasonic treatment to reduce aggregation.
