Silicone rubber (Q) is a special rubber with silicon and oxygen atoms in the main chain, of which the silicon element plays a major role. Its main feature is both high temperature resistance (maximum 300℃) and low temperature resistance (minimum -100℃). It is currently the best high temperature resistant rubber. At the same time, it has excellent electrical insulation and high stability to thermal oxidation and ozone. , Chemically inert. The disadvantage is that the mechanical strength is low, oil resistance, solvent resistance, acid and alkali resistance are poor, it is difficult to vulcanize, and the price is more expensive. Operating temperature: -60℃~+200℃. It is mainly used to make high and low temperature resistant products (hose, seals, etc.), high temperature resistant wire and cable insulation layer. Because it is non-toxic and tasteless, it is also used in the food and medical industries.
