Product Description
China fumed silica TS-720 PDMS amorphous powder hydrophobic fumed silica HB 139 for cosmetics
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.

Characteristics of HB-139
HB-139 is hydrophobic fumed silica which is produced by hydrophilic fumed silica with specific surface area of 200m2/g after chemical post-treatment with PDMS (Polydimethylsiloxane).
