Feature
It Is Made of High-quality Fluorine Rubber (Also Known As Fkm or Fpm) Material, Environmentally Friendly, Non-toxic, Smooth and Sensitive Surface, Good Elasticity, High Stability, Good Electrical Insulation, Ozone Resistance, Aging Resistance, Acid and Alkali Resistance, Corrosion Resistance and Waterproofing. It Has Good Impact Resistance and Can Be Used As a Cushioning Material.

Application
It Is Widely Used in Aerospace, Automotive, Petroleum, Chemical, Telecommunications and Other Industries. It Can Be Processed into Hoses, Tapes, Films, Seals, Oil Seals, "O" Rings, "V" Rings, Etc.

Performance:
Fluorine Rubber Has a High Degree of Chemical Stability and Is the Best Medium Resistance Among All Elastomers. Type 26 Fluororubber Is Resistant to Petroleum Base Oil, Diester Oil, Silicone Ether Oil and Silicic Acid Oil. Resistant to Inorganic Acids, Most Organic and Inorganic Solvents, Chemicals, Etc., but Not Resistant to Low-molecular Ketones, Ethers and Other Esters, and Not Resistant to Amines, Ammonia, Hydrofluoric Acid, Chlorosulfonic Acid, and Phosphoric Acid Hydraulic Oil. Type 23 Fluoroelastomer the Performance of the Medium Is Similar to That of Type 26, Which Is More Unique. the Resistance to Strong Oxidizing Inorganic Acids Such As Fuming Nitric Acid and Concentrated Sulfuric Acid Is Better than That of Type 26. Immerse in 98% Hno3 at Room Temperature. 27 Its Volume Expansion Is Only 13%~15%.

Main Purpose:
Fluorine Rubber Seals, When Used for Engine Sealing, Can Work for a Long Time at 200℃～250℃, and Can Work for a Short Time Below 300℃. Its Working Life Can Be the Same As the Engine Maintenance Life, Reaching 1,000 to 5,000 Flight Hours (5 to 10 Years); When Used in the Chemical Industry, It Can Seal Inorganic Acids (Such As 67% Sulfuric Acid at 140°C, Concentrated Hydrochloric Acid at 70°C, and 30% Nitric Acid) ), Organic Solvents (Such As Chlorinated Hydrocarbons, Benzene, Highly Aromatic Gasoline) and Other Organic Substances (Such As Butadiene, Styrene, Propylene, Phenol, Fatty Acids at 275°C, Etc.); When Used in Deep Well Oil Production, It Can Withstand the Harsh Working Conditions of 149°C and 420 Atmospheres; When Used for the Overheating of the Steam Seal, It Can Work for a Long Time in the Steam Medium of 160~170°C. in the Production of Monocrystalline Silicon, Fluorine Rubber Seals Are Often Used to Seal Special Media at High Temperatures (300°C)-Trichlorosilane, Silicon Tetrachloride, Gallium Arsenide, Phosphorus Trichloride, Trichloroethylene and 120°C Hydrochloric Acid Wait.
