What is perfluororubber? Perfluoroelastomer is a synthetic rubber containing fluorine atoms. It has excellent heat resistance, oxidation resistance, oil resistance and chemical resistance. It is mainly used in aviation, chemical, petroleum, automotive and other industrial sectors as a sealing material and medium. Materials and insulation materials. A synthetic rubber containing a fluorine atom in its molecular structure.

It is usually indicated by the number of fluorine atoms of the fluorine-containing unit in the copolymer, such as fluororubber 23, which is a copolymer of vinylidene fluoride and chlorotrifluoroethylene. Fluororubber is resistant to high temperatures, oils and chemicals. Fluororubber 23, commonly known as No. 1 glue in China, is a copolymer of vinylidene fluoride and chlorotrifluoroethylene. Fluororubber 26, commonly known as No. 2 rubber in China, DuPont trademark VITON A, is a copolymer of vinylidene fluoride and hexafluoropropylene, and its comprehensive function is better than No. 1 rubber. Fluororubber 246, commonly known as No. 3 rubber in China, DuPont trademark VITON B, is a vinylidene fluoride, tetrafluoroethylene, hexafluoropropylene terpolymer, fluorine content higher than 26 glue, good solvent resistance. Fluororubber TP, commonly known as tetrapropyl acrylate in China, AFLAS brand is a copolymer of tetrafluoroethylene and propylene propylene, which is superior in water vapor resistance and alkali resistance. The fluoroether rubber, DuPont trademark VITON GLT, is a vinylidene fluoride, tetrafluoroethylene, perfluoromethyl vinyl ether, vulcanization point monomer quaternary copolymer, excellent in low temperature function. Perfluoroether rubber, DuPont trademark KALREZ, excellent in low temperature function, high in fluorine content and excellent in solvent resistance. Fluorosilicone rubber, excellent in low temperature function, with certain solvent resistance. Types of fluorine rubber: The main types of perfluoro rubber are: perfluororubber round, perfluoroelastomer, perfluororubber, perfluororubber, perfluorinated Rubber sheets, etc. Fluororubber properties: Perfluoroelastomer is a white or amber translucent sheet-like elastomer, non-toxic, odorless, non-flammable (self-extinguishing), excellent heat, oil and chemical resistance, outstanding physical and mechanical functions and Weather resistance, can be melted in low molecular ketones and lipids. 1. Withstand voltage: ≥6.0KV 2. Operating temperature: -60+350oC 3. Specific gravity: 2.0 4. Hardness: 70±5 5. Tensile strength: ≥6.5 6. Excellent oil, solvent and ozone resistance Corrosion resistant. Advantages of fluororubber: 1. Excellent high temperature resistance: Operating temperature range from -60 to +250. Excellent oil resistance: For high temperature fuel oil, sulfur oil, hydraulic oil, diester oil, silicate, etc. The oils have better tolerance than other rubbers. 3. Excellent resistance to strong corrosive medium and strong oxidant; stability to strong corrosive media such as fuming nitric acid, concentrated sulfuric acid, hydrochloric acid, hydrogen peroxide, concentrated alkali, etc. are better than other rubbers. 4. Outstanding mechanical function, electrical insulation function and anti-radiation function. 5. Outstanding high vacuum resistance. Fluororubber Applicable Scope: 1. Fluororubber changes little when exposed to moisture or temperature, even if the silica generated by short-circuit incineration is still an insulator, which ensures that electrical equipment continues to operate, so it is suitable to manufacture wires, cables, Lead wire. 2. Perfluoroelastomer tube can be used for fluid transportation and sealing of various strong acid and alkali, steam, hot air, hot oil, etc. It can also be used in home appliances, lighting, medical equipment; 3. Working pressure of perfluororubber tube (0.5-3.0) MPa) Joints and stainless steel mesh cover can be added. 4. Perfluoroethylene strips are also used in harsh wire jackets for working environments. 5. Fluororubber has outstanding high temperature and corrosion resistance, and can be processed into rubber hose, tape, film, gasket, (skeleton) oil seal, "O" ring, "V" ring, etc., widely used in aviation and automobiles. , petroleum, chemical, telecommunications, instrumentation and other areas.
