Functional Glass Spheres

Polymer Additives


By adding glass spheres as polymer additives, plastic polymers will be applied a variety of functional properties. Glass spheres are hard and have low thermal expansion characteristics so that they not only prevent distortion and strain while plastics shrink but also improve strength. Addition of appropriate types of glass spheres enables plastics to obtain such properties as surface hardness, matte finish, weight reduction, noise insulation, and heat insulation.


Isotropic, easy flow, counter-measure of plastic deformation and ideal for precise molding

High-performance glass beads available for matte finishing and hardening

Various type of hollow glass spheres are available for high performance applications such as weight reduction, thermal insulation, etc.

A variety of conductive fillers created by Potters' coating technology are available.

Differences in strain distribution in resin due to various fillers

The distortion of plastic depends on the shape of the filler material. Glass spheres are isotropic, so they can distribute strain evenly and improve dimensions stability.
