Knowledge of special rubber

　　Special rubber is also called special synthetic rubber. It refers to synthetic rubber with special properties and special uses that can be used under harsh conditions. For example, 300 centigrade high temperature, strong corrosion resistance, ozone resistance, light, weather, radiation and oil resistant fluoroelastomer, -100 C, low temperature and 260 C high temperature, low temperature dependence, low viscous flow activation energy and physiological inertia of silicone rubber; heat resistant, solvent resistant, oil resistant, good electrical insulation propionate rubber. There are other polyurethane rubber, polyether rubber, chlorinated polyethylene, chloro sulfonated polyethylene, epoxy propane rubber, polysulfide rubber and so on. They also have excellent unique properties. They can meet the specific requirements that general rubber is incompetent, and have the emphasis in the fields of national defense, industry, advanced science and technology, medical and health. It's going to work.
