Product Description

Product Description

Pyrogenic silica hydrophilic fumed silica 200 with CAS 7631-86-9

Fumed silica, also known as pyrogenic silica, because it is produced in the flame. It is superfine micro-nano fine chemical products with primary particle size 5 -50 nm, which is divided into hydrophilic type and hydrophobic type according to their different surface treatment process.

 

Fumed silica is widely applied to the industries of silicone rubber, adhesives, sealants, paint, coating, resins, pharmaceuticals, composite materials, fertilizer, animal feed and food etc.
