(1) fluorine rubber: good resistance to high temperature, can be used-30 ℃-+ 250 ℃ environment, strong oxidizing agents, which can withstand oil, acid, and alkali-resistant. Usually used for high temperature, high vacuum and high-pressure environments, suitable for oil environment. Due to its excellent performance, fluoro rubber is widely used in petroleum, chemical industry, aviation, and aerospace sector.
(2) silicone rubber: has outstanding resistance to high and low-temperature performance,-70 ℃-+ 260 ° c temperature range to maintain good flexibility and advantages such as resistance to ozone and aging, preferably made of the Thermo-mechanical seal. Toxicity can be made with no insulation, insulation products, and rubber products.
3, NBR: has excellent aromatic oils and solvent-resistant properties, but is not resistant to ketones, esters and chlorinated by the media, so oil-seals NBR-oriented products.
4, CR: has good oil resistance, solvent resistance, chemical properties, but not resistant to aromatic oils, which is characterized by excellent resistance to weather aging and ozone aging. Neoprene is usually used in making doors and Windows sealed and the diaphragm and sealing products for General vacuum;
5, EPDM: good resistance to temperature, whether aging and ozone aging, usually doors and Windows sealed and widely used in the automotive industry.
6, PTFE gasket is with PTFE material from the original and high-quality synthetic rubber, using a special production process a new seal is a composite material, which combines the excellent properties of PTFE and rubber, making the product has excellent resistance to both corrosion and heat-resistant, toxic, viscous resistance, but also has good elasticity and tightness.
