Using graft polymerization of fumed silica surface modification using polymer macromolecular chains to effectively block nanoparticles reduce their agglomeration and then filled polypropylene with silica manufacturers, prepared by blending technology integrated high performance fumed nano Si02 / PP composites. At low amount of the silica companies can improve the toughness of polypropylene about twice. If the composite system in an appropriate amount of added elastomer, polypropylene while maintaining the rigidity and tensile strength, ability to make anti-notched impact polypropylene increased by about three times, analysts believe that the fumed silica and the elastomer can be synergistic two silicon oxide, the purpose of toughening polypropylene. The added advantage of blending fumed silica nano PMMA prepared Si02 / PMMA plastics, can significantly improve the performance of the material. When you add the amount of 4%, the notched impact strength of PMMA can increase sales up more than 80 percent silica, and a composite material having a good optical transparency. In most microelectronic process temperature range of interest, the crystallization rate of silica to be ignored. Although fused quartz silica structure is not long range order, but it showed a short ordered structure, its structure can be considered as the four oxygen atoms are located tetrahedron vertices. Polyhedron center is a silicon atom. Silica products, Weifang Fuyuan (certified), silica provided by Weifang Fuyuan Environmental Technology Limited.
