Performance of rubber products

Rubber products refer to rubber products with certain special properties. Mainly including: ① Neoprene rubber products. CR, abbreviated as CR, is obtained by polymerization of chloroprene. It has good comprehensive performance, including oil resistance, flame resistance, oxidation resistance, and ozone resistance. But its density is relatively high, it is prone to crystallization and hardening at room temperature, has poor storage performance, and poor cold resistance Nitrile rubber products. NBR, abbreviated as NBR, is obtained by copolymerization of butadiene and acrylonitrile. Good oil and aging resistance, suitable for long-term use in air at 120 ℃ or oil at 150 ℃. In addition, it also has water resistance, air tightness, and excellent bonding performance Silicone rubber products. The main chain is composed of alternating silicon and oxygen atoms, with organic groups on the silicon atoms. High and low temperature resistance, ozone resistance, and good electrical insulation. ④ Fluorine rubber products. Synthetic rubber products containing fluorine atoms in their molecular structure. Usually represented by the number of fluorine atoms in the fluorine containing unit of the copolymer, such as fluorine rubber product 23, which is a copolymer of vinylidene fluoride and trifluoroethylene chloride. Fluorine rubber products are resistant to high temperature, oil, and chemical corrosion. ⑤ Polysulfide rubber products. It is formed by condensation of dihaloalkanes with polysulfides of alkali or alkaline earth metals. It has excellent oil and solvent resistance, but its strength is not high, its aging resistance and processability are not good, and it has a foul odor. It is often used in combination with nitrile rubber products. In addition, there are also polyurethane rubber products, chlorohydrin rubber products, acrylic rubber products, etc.
