In plastics and other polymer blends. Fumed silica can be added to improve the compatibility of the two phases. As to the Ps and PP blends of ultrafine silica manufacturers, joined by styrene or methyl chloride silane-modified fumed silica, it can reduce the interfacial tension between phases, so that the cloud point temperature drop, improve the two-phase compatibility. Add fumed silica in the epoxy resin can significantly improve their brittleness, stiffness and strength can overcome the material to reduce defects caused elastomer toughened to achieve the purpose of toughening. When the addition amount of ultrafine silica 3wt% high volume, complex systems can impact strength increased by 40%, the tensile strength by 21%. If by coupling of nano-silica was modified so that it can be 124% and toughness, tensile properties increased by 30%, In addition, the hardness, wear resistance, heat resistance and insulation properties of the article is improved. The application in putty Putty Putty is an unsaturated polyester resin as the main body, with a short curing time, solvent resistance, durability, no cracking, high strength series of advantages of ultrafine silica, widely used automobile and other machinery industry. Putty with a physical presence in the production of instability, namely sedimentation stability of ultrafine silica companies and large, in order to improve the sedimentation stability of the system, should be added to the anti-settling agent. In a common anti-settling agent, fumed silica is better, with good anti-settling effect and excellent thixotropy. Low price of ultrafine silica, ultra-fine silica, Weifang Weifang Fuyuan Fuyuan provided by the Environmental Protection Technology Co., Ltd.
