6um Spacer PS Microspheres PAPS6UM

6um Spacer PS Microspheres PAPS6UM

SHBC PAPS6UM are precision-manufactured 6 μm polystyrene microspheres developed for gap control, thickness control and micron-level spacing.

The uniform spherical particles help maintain a defined distance between substrates, films, coatings and bonded components. PAPS6UM is suitable 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 provided in the product specification or Certificate of Analysis.

Key Features

Precise 6 μm Gap Control

The controlled particle diameter helps form a defined micron-level gap between two surfaces or functional layers.

Uniform Spherical Morphology

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

Controlled Particle Size Distribution

Consistent particle sizing supports repeatable spacing performance and stable manufacturing processes.

Smooth Particle Surface

The smooth particle surface supports uniform distribution in compatible adhesives, coatings, sealants and functional materials.

Stable Polystyrene Structure

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

Reliable Batch Consistency

Controlled production supports stable particle size and repeatable performance from sample testing to bulk manufacturing.

How 6um Spacer Microspheres Work

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

During assembly, the microspheres act as physical support points. Their diameter helps determine the final separation distance while reducing direct contact between the two surfaces.

PAPS6UM is designed for systems requiring an approximately 6 μm spacing layer.

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 glass and light-control structures requiring uniform layer separation.

Optical Films and Components

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

Adhesive Gap Control

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

Touch Panels and Sensors

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

Semiconductor Assembly

Can be evaluated for controlling adhesive thickness and spacing between chips, substrates and packaging materials.

Advantages for Manufacturers

PAPS6UM helps support:

• Controlled 6 μm spacing

• Uniform layer thickness

• Reduced direct substrate contact

• Consistent particle distribution

• Repeatable assembly processes

• Improved production uniformity

• Customized material development

• Sample-to-bulk scale-up

Recommended Use

Disperse the microspheres evenly in the selected carrier, adhesive, coating or solvent before application.

Important processing factors include:

• Carrier compatibility

• Microsphere concentration

• Material viscosity

• Dispersion time

• Ultrasonic conditions

• Coating or spraying method

• Assembly pressure

• Target particle density

Gentle mixing or controlled ultrasonic dispersion can be used to reduce particle aggregation. Final conditions should be optimized for the customer’s formulation and manufacturing process.

Adhesive Gap-Control Applications

When PAPS6UM is added to an adhesive, the particles form physical support points during bonding.

The recommended microsphere loading depends on:

• Bonding area

• Adhesive volume

• Dispensing method

• Required support-point density

• Assembly pressure

• Target bond-line thickness

Process validation is recommended before industrial production.
