Product Description
Fumed silica hydrophilic fumed silica 90 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.
