Our XYSIL® fumed silica is white, innoxious, insipid, amorphous fine chemical powder. XYSIL® fumed silica has many features such as small partical size, large BET surface area, high surface activity and high purity. The original particle size can be 7-40 NM according to system setting, and the BET surface area is 70 – 40 m2/g. Because of nano-meter effect, XYSIL® fumed silica performs excellent nature of reinforcing, thickening, thixotropy, insulation, matting, resist sagging, it is widely used in High Temperature Vulcanization(HTV) Silicone Rubber and Room Temperature Vulcanization(RTV) Silicone Rubber, coating, paints…
Xunyuchem also developed hydrophobic fumed silica products to meet customers’ need, and the main grades of hydrophobic fumed silica are: XYSIL® R120, XYSIL® R170 and XYSIL® R200. These hydrophbic products are after-treated with HMDS (hexamethyldisilazane) and DDS (Dimethyldichlorosilane), or structured modified. Complete product line of XYSIL® provides strong power for consumers’ innovation.
