Applications use fumed silica of high strength, high mobility and small size effect in plastics, plastic products can increase the density, smoothness and wear resistance. If by suitable surface modification, you can achieve the purpose of the plastic while enhancing toughening. Add the fumed silica to precipitated silica polyethylene company is large in scale, precipitated silica manufacturers through a special process which allows the silica in the matrix dispersed precipitated silica Which is good, make high wear resistance, high hardness, polyethylene composites. Silica generally not react with water, i.e., in contact with water does not generate silicic acid, silica but artificially predetermined silicic acid anhydride. Precipitated silica products, Weifang Fuyuan (certified), precipitated silica provided by the Environmental Protection Technology Co., Ltd. Weifang Fuyuan. Weifang Fuyuan Environmental Technology Limited (www.wfdafuyuan.com) (www.wfdafuyuan.com) Shandong Weifang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer demand. In Weifang Fuyuan leadership with the staff warmly welcome all inquiries negotiations to create Weifang Fuyuan better future.
