Silica powder for precision casting

Silica Powder Introduction

Silica powder has the advantages of excellent dielectric properties ,Low coefficient of thermal expansion, Complete chemical inertness and Neutral PH ,No chemical changes or induced reactions occur in either a catalyst or multicomponent.

 Donghai County Chaori Quartz Products Co., Ltd. high purity silica power is produced for the electronic materials area ,sealants, electronic potting compound area .Its dispersion leveling is excellent, contraction and Coefficient of thermal expansion are small, Acid alkali resistance ,solvent insulation,,mechanical performance, Mixed epoxy resin transparency are all good.

In total ,our excellent silica power can save cost and improve effectiveness for you .
