Silicon Dioxide used in Plastic Industry
Silica can be used as filling material in polyethylene, polypropylene, polybutene, epoxy resin and other plastics. It can improve the elastic strength and wear resistance of plastics, as well as the thermal stability of hardness. The cable can also improve the electrical insulation of the cable, for example, the methyl vinyl silicone rubber high pressure line is to use high quality precipitated silica black. Usually,it is not easy to separate between the two layers of plastic film and packing bag, silica is a very useful openning agent. When polyvinyl chloride is used as a household floor material, if a certain white carbon black is added, the properties of the product can be improved, such as hardness, elasticity, thermal denaturation and so on.
