--Product Description
PPT Silica Precipitated Silica Silicone Dioxide Hydrophobic, Defoaming, Leveling, Thickening, Anti-settling
Product Description
∞ Chemical Formula: SiO2 (White Carbon Black)
∞ CAS No:7631-86-9
∞ Feature+Application
It is suitable for textile dyeing and finishing, defoamer, lubricating oil, unsaturated polyester resin, powder extinguisher,
silicone rubber and other products.
Hydrophobic silicon dioxide is the silicon dioxide after special treatment. According to different characteristics of various
industries, general hydrophilic silica is mixed with dimethyldichlorosilane for reaction under appropriate condition, and then the solid powdery silicon dioxide that surface is with polysiloxane is made. Its hydrophobic contact angle can reach 70 to 150. It not only has excellent hydrophobicity but also has the functions of defoaming, thickening, excellent leveling property and anti-settling.
