Fused silica powder
Fused silica is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000℃) to amorphous Silicon dioxide, then it is classed to different grades by manual and then specially engineered to powder by ball mill.
 
Applications:
  • Filler of epoxy molding compound
  • Filler of epoxy potting compound
  • Filler of silicon rubber
  • Filler of functional coating
  • Filler of fusion bonded epoxy powder coating
 
Main Characteristic:
  • lower linear expansion coefficient
  • lower tension & lower radiation
  • it is environmentally, no harm to workers and environment
