Product Description
Pyrogenic silica hydrophilic fumed silica 300 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 ndifferent 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.
