Precipitated Silica  for Paper Making Filler

Precipitated Silica (White Carbon Black) for Paper Producing Filler

Synonyms: SiO2 Powder, White Carbon Black, Precipitated Silica, Silica,Silicon DioXiHu (West Lake),Reinforcing filler…

Chemical Property
It can be dissolved by NaOH, HF.Other varieties of acid, drinking water and solvents cannot dissolve the solution. Resistance to high temperature, no combustion, excellent insulation, odourless properties


1. White Carbon Black (Silicon DioXiHu (West Lake), Hydrated Silica) are a flexible inorganic chemical which are used for reinforcement of rubbers and plastics, coating and paints, printing inks and cosmetics, antiblocking of plastic foils, free running and free stream of sticky solid and liquid substances, provider for pesticides, insecticides, large temperature insulation, stabilizing of beer and silicon rubber.

2. White Carbon Black (Silicon DioXiHu (West Lake), Hydrated Silica) possesses a substantial reinforcing possible and imparts to rubber compounds specifically large Shore hardness, tensile strength, tear resistance and abrasion resistance. In orEPTto attain optimum rubber-complex knowledge the addition of activators like glycols, amines or other alkaline accelerators is necessary.

Fumed silica powEPT(Fumed silica powder)

Productive Process:
Fumed Silica is created with the method of gasoline period . Its theory is burning the chloride unEPToxyhydrogen flame and substantial- temperature vapor section hydrolysis, and gathered concluded product right after refining procedure of condensation, separation, deacidification and screening.

Application Functions:
1.Thickening and thyrotrophic impact

2.Suspension and emulsification
three.Totally free-flowing and anti-caking
four.Anti-slipping operate
five.Extinction result
6.Anti-adhesion influence
seven.EnhXiHu (West Lake) Dis.Hu (West Lake) reinforcement result
