15um Spacer PS Microspheres PAPS15UM 10%

15um Spacer PS Microspheres PAPS15UM

SHBC PAPS15UM are precision 15 μm polystyrene microspheres developed for gap control, layer separation and bond-line thickness control.

The uniform spherical particles act as physical support points between substrates, films and bonded components. PAPS15UM can be used in LCD, PDLC, smart glass, optical materials, adhesive bonding and precision electronic assembly.

Product Specifications

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

Key Advantages

Precise 15 μm Spacing

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

Uniform Spherical Morphology

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

Controlled Particle Size

Consistent particle sizing supports repeatable gap formation and more uniform assembly results.

Smooth Particle Surface

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

Polymer Spacer Material

The PS structure provides physical support while offering lower hardness than many inorganic spacer materials.

Stable Batch Supply

SHBC supports samples, pilot orders, customized specifications and bulk manufacturing.

Main Applications

LCD Cell Gap Control

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

PDLC and Smart Glass

Suitable for polymer-dispersed liquid crystal films and switchable glass requiring controlled layer separation.

Adhesive Gap Control

Added to compatible adhesives or sealants to help maintain an approximately 15 μm 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 controlled spacing between glass, films, sensors and electronic components.

Electronic Assembly

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

How 15um Spacer Microspheres Work

PAPS15UM microspheres are dispersed in a compatible carrier or placed between two surfaces.

During assembly, the particles act as physical support points. Their nominal 15 μm diameter helps define the final separation distance and reduces direct contact between the substrates.

Product Benefits

PAPS15UM helps provide:

• Controlled 15 μm spacing

• More uniform layer thickness

• Consistent support-point distribution

• Reduced local gap variation

• Repeatable bonding processes

• Compatibility with multiple material systems

• Custom specification options

• Scalable industrial supply

Dispersion and Processing

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

Important processing factors include:

• Carrier compatibility

• Particle concentration

• Material viscosity

• Dispersion time

• Ultrasonic conditions

• Coating or dispensing method

• Assembly pressure

• Required support-point density

Use gentle mixing or controlled ultrasonic dispersion to reduce aggregation. Final processing conditions should be optimized for the customer’s formulation.

Adhesive Gap-Control Guide

When PAPS15UM is mixed into an adhesive, the particles provide mechanical support during bonding.

The recommended particle loading depends on the bonding area, adhesive volume, dispensing method, assembly pressure and required support-point density.

Material compatibility and process validation are recommended before production use.
