1. Bromobutyl rubber: The mass fraction of bromine is 1.5 to 2.5%. The scale of a single unit reached 30,000 tons/year.
2. Hydrogenated nitrile rubber: low temperature resistance up to -50 °C, high temperature conventional use temperature is 150 °C. The scale of a single unit is up to 1,000 tons per year.
3. Fluororubber: It can be used at 200 °C for a long time, short-term use at 250 °C, and the brittle point is between -20 and -40 °C. It has excellent oil and chemical resistance and is suitable for vehicles close to the engine. High temperature resistant, oil resistant rubber parts. The scale of a single unit is 5,000 tons/year.
4. Special silicone rubber: special silicone rubber such as liquid silicone rubber and phenyl silicone rubber. It has excellent high temperature resistance, pressure resilience and human inertia. It can be used for a long time in the wide temperature range of -150～250 °C. . The scale of a single set of equipment reaches 10,000 tons/year.
5. Isoprene rubber and monomer: cis-isoprene rubber content ≥98%, can replace natural rubber, the scale of single-set device reaches 30,000 tons/year; trans-isoprene rubber industrialization, single-unit device scale 30,000 tons / year. The eucommia gum reaches 100 tons/year and needs to be comprehensively utilized.
6. Acrylate rubber: Acrylate rubber for auto parts. Its oil resistance is similar to that of nitrile rubber. Its high temperature resistance is better than hydrogenated nitrile rubber. The temperature is -20~80 °C. The scale of a single unit is 5,000 tons/year.
