2um Spacer PS Microspheres PAPS2UM

2umsion-manufactured 2 μm polystyrene microspheres designed for micron-level spacing and gap control.

Their uniform spherical morphology helps maintain consistent separation between substrates, films or functional layers. PAPS2UM is suitable for LCD, PDLC, optical materials, microelectronic assembly and precision spacer research.

Product Specifications

Batch-specific particle size distribution, solid content, dispersion medium and storage conditions are available in the product specification or Certificate of Analysis.

Key Features and Advantages

Precise 2um Spacer Size

The controlled 2 μm particle size is suitable for thin-gap structures requiring micron-level spacing.

Uniform Spherical Morphology

Regular spherical particles support more consistent contact points and reduce local spacing variation.

Narrow Particle Size Distribution

Controlled particle uniformity helps improve gap consistency and process repeatability.

Smooth Particle Surface

The smooth microsphere surface supports uniform distribution within coatings, adhesives and functional materials.

Stable Polystyrene Structure

The PS matrix provides reliable particle integrity during material preparation and spacer application.

Reliable Batch Consistency

Controlled manufacturing supports stable particle size and product performance between production batches.

Spacer Microsphere Working Principle

Spacer microspheres are distributed between two substrates or material layers.

When the layers are assembled, the microspheres act as physical spacing points. Their diameter helps define the final gap thickness and prevents direct contact between the two surfaces.

The 2 μm particle size makes PAPS2UM suitable for applications requiring a thin and controlled separation layer.

Main Applications

LCD Cell Gap Control

Used as spacer particles between LCD substrates to help maintain a uniform liquid crystal cell gap.

PDLC Films

Suitable for polymer-dispersed liquid crystal materials requiring controlled film thickness and consistent spacing.

Display Panel Manufacturing

Supports precision separation between glass, polymer or functional display layers.

Optical Films and Coatings

Used to control coating thickness or layer separation in optical material development.

Precision Adhesive Gap Control

Added to adhesives or bonding materials to help maintain a defined bonding thickness.

Microelectronic Assembly

Suitable for micron-level spacing, structural support and gap-control research in electronic component assembly.

Spacer Material Research

Can be used for evaluating particle distribution, substrate spacing and thin-layer fabrication processes.

Why Choose 2um PS Spacer Microspheres?

The 2 μm size is designed for thin-gap applications where larger spacer particles may create excessive separation.

Key benefits include:

• Precise micron-level gap control

• Uniform spherical particle shape

• Consistent spacing performance
