Product Description

Introduction:
Fumed Silica is produced with the method of gas phase . Its   theory is burning the chloride under oxvhydrogen flame and high- temperature vapor         phase hydrolysis, and collected finished product after refining process of condensation, separation, deacidification and screening. Fumed silica, commonly known as "fumed white carbon black", is widely used in various industries as additives, catalyst carriers, petrochemicals, decolorizers, matting agents, rubber reinforcing agents, plastic fillers, ink thickeners, metal soft Sexual polishing agent, insulating filler, advanced daily cosmetic filler and spraying material, medicine, environmental protection and other fields. It also provides a new material foundation and technical guarantee for the development of related industrial fields.

Application Features:
1.Thickening and thyrotrophic effect
2.Suspension and emulsification
3.Free-flowing and anti-caking
4.Anti-slipping function
5.Extinction effect
6.Anti-adhesion effect
7.Enhancing reinforcement effect

Application in Industry:
1.Heat preservation and heat insulation materials
2. Adhesives and Sealants 
3.Ink,Paints and coatings
4.Silicone Rubber
