Fluorine rubber is resistant to high temperature, can be used in the environment of -30℃-+250℃, and is resistant to strong oxidant, oil and acid and alkali. Usually used in high temperature, high vacuum and high pressure environment, suitable for oil environment. Fluorocarbon is widely used in petroleum, chemical, aviation, aerospace and other departments because of its excellent performance.

Other materials of rubber sealing ring:
1. Silicone rubber: It has outstanding high and low temperature resistance, good elasticity in the temperature range of -70℃-+260℃, ozone resistance, weathering resistance and other advantages, and is suitable for sealing gaskets in thermal machinery. Because it is non-toxic, it can be used to make heat insulation and insulating products and medical rubber products.
2. NBR: It has excellent oil resistance and aromatic solvents, but it is not resistant to ketones, esters and chlorinated solvents, so NBR is the main oil-resistant sealing product.
3. Neoprene rubber: It has good oil resistance, solvent resistance and chemical medium resistance, but it is not resistant to aromatic oil. It is characterized by excellent weathering and ozone aging resistance. In production, chloroprene rubber is usually used to make sealing strips and diaphragms for doors and windows and general vacuum sealing products;
4. EPDM: It has good temperature resistance, weather resistance and ozone aging performance, and is usually the most widely used in door and window sealing strips and automobile industry.
5. PTFE composite gasket is a new sealing material made of PTFE and high-quality synthetic rubber through a special production process. It combines the excellent characteristics of PTFE and rubber, so that the product not only has excellent corrosion resistance, but also has high temperature resistance, non-toxicity, anti-adhesion, elasticity and sealing performance.
