Characters

Fumed Silica is type of white, non-toxic, odourless and amorphousinorganic fine chemistry products which is made of the chlorosilanewith the pyrohydrolysis under the oxy-hydrogen flame state. OurHS971,HS973 and HS975 are all hydrophilic types.

Applications

1. Strengthen the fillers in the silastic system(HTV,RTV)
2. Control the flowing property in the adhesive and sealantsystem
3. Anti-deposit property,anti-flowing property andanti-thixotropic in the coatings,oil ink system.
4. Electronic products, paper, medicine,cosmetic,toothpaste,plastic applications.
