Introduction Of Perfluorinated Rubber

- Nov 22, 2019-

What is perfluoro rubber Perfluorinated rubber is a kind of synthetic rubber containing fluorine atoms. It has excellent heat resistance, oxidation resistance, oil resistance and drug resistance. It is mainly used in aviation, chemical industry, petroleum, automobile and other industrial sectors as sealing materials, medium resistant materials and insulation materials. Synthetic rubber containing fluorine atom in molecular structure.

It is usually indicated by the number of fluorine atoms in the fluorine-containing unit of the copolymer, for example, fluororubber 23 is a copolymer of vinylidene fluoride and trifluoroethylchloride. Fluororubber is resistant to high temperature, oil and chemical corrosion Fluororubber 23, commonly known as No. 1 rubber in China, is a copolymer of vinylidene fluoride and trifluoroethylene chloride Viton a, a trademark of DuPont, is a copolymer of vinylidene fluoride and hexafluoropropylene. Its comprehensive function is better than that of No. 1 rubber Fluororubber 246, commonly known as No. 3 rubber in China, is a terpolymer of vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene, with fluorine content higher than 26 rubber, and good solvent resistance Fluororubber TP, commonly known as tetrapropylene rubber, Asahi brand aflas, is a copolymer of tetrafluoroethylene and hydrocarbon propylene, with superior water vapor and alkali resistance Vinylidene fluoride ether rubber, DuPont trademark Viton GLT, is a quaternary copolymer of vinylidene fluoride, tetrafluoroethylene, perfluoromethylvinyl ether and vulcanization point monomer, with excellent low-temperature function Perfluoroether rubber, DuPont trademark kalrez, excellent low temperature function, high fluorine content, excellent solvent resistance Fluorosilicone rubber, with excellent low temperature function, has certain solvent resistant function. The main types of perfluoro rubber are: perfluoro rubber round bar, perfluoro rubber round tube, perfluoro rubber square bar, perfluoro rubber special-shaped bar, perfluoro rubber plate, etc Characteristics of fluororubber: it is a white or amber translucent sheet elastomer, non-toxic, tasteless, non combustible (self extinguishing), with excellent heat resistance, oil resistance, chemical resistance, outstanding physical and mechanical functions and weather resistance, and can be melted in low molecular ketones and lipids 1. Withstand voltage: ≥ 6.0KV 2. Operating temperature: - 60 + 350oC 3. Specific gravity: 2.04. Hardness: 70 ± 5 5. Tensile strength: ≥ 6.56. Excellent oil resistance, solvent resistance, ozone resistance and corrosion resistance Advantages of fluororubber: 1. Excellent high temperature resistance function: the application temperature range is from - 60 to + 250. Excellent oil resistance function: the resistance function of high temperature fuel oil, sulfur-containing lubricating oil, hydraulic oil, diester oil, silicate ester and other oils is better than other rubbers 3. Excellent strong corrosion resistance medium and strong oxidant function; the stability of strong corrosion medium such as fuming nitric acid, concentrated sulfuric acid, hydrochloric acid, hydrogen peroxide, concentrated alkali is better than other rubbers 4. Excellent mechanical function, electrical insulation function and radiation resistance function 5. Excellent high vacuum resistance Application scope of fluororubber: 1. When the fluororubber is damped or the temperature rises, the change is small, even if the silicon dioxide generated by short-circuit incineration is still the insulator, which ensures that the electrical equipment continues to work, so it is suitable to manufacture wires, cables and lead wires 2. The perfluorinated rubber tube can be used for conveying and sealing various strong acid and alkali, steam, hot air, hot oil and other fluids, and also can be used for household appliances, lighting, medical devices; 3. The working pressure of the perfluorinated rubber tube (0.5-3.0 MPa) can be added with joint and stainless steel mesh cover 4. The perfluorinated rubber strip is also used for the wire jacket with harsh working environment. 5. Fluororubber has outstanding high temperature and corrosion resistance function, and can be processed into rubber tube, rubber cloth, film, gasket, (framework) oil seal, "O" ring, "V" ring, etc., which are widely used in aviation, automobile, petroleum, chemical industry, telecommunication, instrument and other fields.
