1 fluorine rubber: with high temperature resistance, can be used in the environment of -30 degrees -+250 degrees, strong oxidation resistance, oil resistance, acid and alkali resistance. It is usually used in high temperature, high vacuum and high pressure environment, suitable for oil environment. Because of its excellent properties, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other sectors.
2 silicone rubber: with outstanding high and low temperature performance, in the temperature range of -70 degrees -+260 degrees Celsius to maintain good flexibility, and has the advantages of ozone resistance, weather resistance aging, should be used as thermal mechanical gasket. Because of no toxicity, insulation, insulation products and medical rubber products can be made.
3, nitrile rubber: excellent oil resistance and aromatic solvents and other properties, but not resistant to ketones, esters and chlorinated medium, so the oil sealed products to use nitrile rubber as the main.
4, chloroprene rubber: with good oil resistance, solvent resistance, chemical medium and other properties, but not resistant to aromatic oil, which is characterized by aging and ozone aging performance is good. In the production, usually the color experience neoprene production doors and windows sealing strip and diaphragm and general vacuum sealing products;
5, three yuan EPDM: has good resistance to temperature, weather aging and ozone aging performance, usually doors and windows sealing strip, the most widely used in the automotive industry.
6, PTFE gasket: with PTFE and high quality rubber material, the special production process of new sealing material compound and into, it has good comprehensive characteristics of PTFE and rubber, the products possess excellent corrosion resistance, and high temperature resistant, non-toxic, anti adhesive, and has good elasticity and tightness
