Xunyu Chemical introduces the Gas-Phase manufacturing technique, which includes seven courses: Pretreatment of raw material, Aggregate, Gas-Soids Separation, Deacidify, Packing, Waste gas treatment.
By hydrolyzing SiCl4 , a byproduct in the procedure in production of polysilicon, in oxyhydrogen flame at high temperature, we get the Primary particles, a particle of 7-40nm. The Primary particles forms agglomerate measured by micron, after being accumulated and collided, the agglomerate and the waste gas produced in the production of Primary particles at high temperature, go into the high efficiency separator, which is called the gas-solid separation. SiO2 from the bottom of the High Efficiency Separator goes into the Deacidiy Tower to deacidify, after that, the products...
Henan Xunyu Chemical Co., Ltd. is a high tech enterprise dedicated to research, manufacture and marketing of fumed silica. We have implemented the most advanced manufacturing techniques in a complete production system, backed up by first class laboratory facilities to provide world class products.

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.
