Divided into natural rubber and synthetic rubber;
The second is divided into general rubber and special rubber according to different uses;
Name English abbreviation of the name

Special rubber mainly includes:
1. Silicon dioxide, Slicone rubber is odorless, non-toxic, not afraid of high temperature and cold characteristics, at 300 degrees Celsius and minus 90 degrees Celsius, "calm", "face color", without losing the original strength and elasticity. Silicone rubber also has good electrical insulation, oxygen resistance and anti-aging, light resistance and anti-mildew, chemical stability
2. There are three main types of fluororubber: fluororubber 23, commonly known as No. 1 rubber in China, which is a copolymer of vinylidene fluoride and trifluoro vinyl chloride; Fluorine rubber 26, commonly known as No. 2 rubber in China, DuPont brand VITONA, is a vinylidene fluoride and hexafluoropropylene copolymer, the comprehensive performance is better than No. 1 rubber; Fluorine rubber 246, commonly known as No. 3 rubber in China, DuPont brand VITONB, is a terpolymer of vinylidene fluoride, tetrafluoroethylene, hexafluoropropylene, fluorine content is higher than 26 rubber, good solvent resistance. Good chemical stability, excellent high temperature resistance, good aging resistance, excellent vacuum performance, mechanical, electrical, breathable, radiation resistance and other properties are strong
3. urethane rubber UR has good wear resistance, followed by good elasticity, high hardness, oil resistance and solvent resistance. The disadvantage is poor heat aging performance
4. neoprene CR has good wear resistance and is used as a pad
Chlorosulfonated polyethylene CSM has good cold resistance
5. Polytetyafluoroethylene PTFE plastic king, excellent acid and alkali resistance, can resist fluorine acid. Widely used, can be used as corrosive liquid pipeline
