9um Spacer PS Microspheres PAPS9UM

9um Spacer PS Microspheres PAPS9UM

SHBC PAPS9UM are precision 9 μm polystyrene microspheres developed for micron-level spacing, gap control and thickness control.

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

Product Specifications

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

Key Advantages

Precise 9 μm Gap Control

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

Uniform Spherical Particles

Regular spherical morphology provides consistent support points and helps reduce local thickness variation.

Controlled Particle Size Distribution

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

Smooth Particle Surface

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

Stable Polystyrene Structure

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

Reliable Batch Supply

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

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

Touch Panels and Sensors

Suitable for structures 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 9um Spacer Microspheres Work

PAPS9UM microspheres are dispersed in a compatible carrier or positioned between two surfaces.

During assembly, the particles act as physical support points. Their nominal 9 μm diameter helps define the final separation distance and prevents direct contact between the two substrates.

Benefits for Manufacturers

PAPS9UM helps support:

• Controlled 9 μm spacing

• Uniform layer thickness

• Consistent spacer distribution

• Reduced local gap variation

• Repeatable assembly processes

• Compatibility with different 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 aggregation. Final conditions should be optimized according to the customer’s formulation and manufacturing process.

Adhesive Gap-Control Applications

When mixed into an adhesive, PAPS9UM 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

Material compatibility and process validation are recommended before production use.
