Key Advantages
Controlled 80 μm Spacing
The nominal particle diameter helps maintain a defined gap between substrates, components and bonded surfaces.
Uniform Spherical Morphology
Regular spherical particles provide stable support points and help reduce local bond-line variation.
Controlled Particle Distribution
Consistent particle sizing supports repeatable thickness control and assembly performance.
Smooth Particle Surface
The smooth surface supports dispersion in compatible adhesives, sealants, coatings and polymer systems.
Lightweight Polymer Structure
Polystyrene provides a lower-density spacer option compared with many inorganic particles, helping reduce settling in suitable formulations.
Scalable Supply
SHBC supports samples, pilot-scale orders, customized specifications and bulk production.
Main Applications
Adhesive Bond-Line Control
PAPS80UM can be added to compatible adhesives or sealants to help maintain an approximately 80 μm bond line.
Camera Module Assembly
Used to control adhesive thickness and component spacing in camera, imaging and optical modules.
Optical Component Bonding
Suitable for spacing between lenses, filters, glass substrates, optical films and other precision components.
Sensor Manufacturing
Can be evaluated in pressure, optical and electronic sensors requiring uniform adhesive thickness.
Semiconductor Packaging
Used for controlling spacing between chips, substrates and packaging components.
Electronic Component Assembly
Suitable for circuit boards, housings, connectors and components requiring a defined assembly gap.
Flexible Electronic Devices
Can be evaluated for controlling electrode or functional-layer spacing in flexible electronic structures.
How 80um Spacer Microspheres Work
PAPS80UM microspheres are mixed into an adhesive, coating or compatible carrier.
During assembly, the particles form physical support points between two surfaces. Their nominal diameter limits excessive compression and helps control the final separation distance.
The actual gap may also be affected by:
Particle size distribution
Maximum particle diameter
Particle concentration
Adhesive viscosity
Assembly pressure
Substrate flatness
Product Benefits
PAPS80UM helps provide:
Controlled 80 μm spacing
Uniform adhesive thickness
Consistent support-point distribution
Reduced local gap variation
Improved component alignment
Repeatable bonding processes
Custom specification options
Reliable bulk supply
Adhesive Processing Guide
Disperse the microspheres evenly in the adhesive before dispensing, coating or bonding.
Important processing factors include:
Adhesive compatibility
Microsphere concentration
Adhesive viscosity
Mixing speed
Dispensing equipment
Bonding area
Assembly pressure
Required support-point density
Gentle mechanical mixing is recommended to minimize air introduction. Avoid excessive mixing that may create bubbles or affect adhesive performance.
Particle Loading Considerations
The required microsphere concentration depends on the bonding area, adhesive volume and number of support points needed.
Insufficient loading may result in uneven gap control. Excessive loading may affect adhesive flow, dispensing and bond strength.
Customers should evaluate:
Dispersion uniformity
Particle settling
Dispensing stability
Final bond-line thickness
Bond strength
Long-term compatibility
Process validation is recommended before production use.
