Precipitated Silica IOTA9002
Introduction:
Use high quality silicon
dioxide as raw material for ultrafine processing to make micron size particles,Close to the fumed silica in
chemical property, With advanced equipment and technology, the product have extremely
narrow particle size distribution and uniform particle size, so the product has
the rare good reinforcement and dispersion. Used in high temperature
rubber and silicone resistant rubber to improve the tearing strength, therefore,
it can Partly instead of fumed silica and lower the cost. It’s an ideal choice.

Applications:
Precipitated silica mainly used
in silicone rubber, silicone rubber intermediate, mold gel, glass glue, aslo
suitable for paint, ink, tyre, sole, coating, cosmetic, pesticide, textile and
toothpaste and etc.
