What is Viton? Fluorine Rubber Properties

2022-10-29

Fluorine rubber is a synthetic rubber containing fluorine atoms, which has excellent heat resistance, oxidation resistance, oil resistance and chemical resistance. It is mainly used in aviation, chemical, petroleum, automobile and other industrial sectors as sealing materials, medium-resistant materials and insulating materials. Synthetic rubber containing fluorine atoms in its molecular structure.

  It is usually expressed by the number of fluorine atoms in the fluorine-containing unit in the copolymer, such as fluororubber 23, which is a copolymer of vinylidene fluoride and chlorotrifluoroethylene. Fluorine rubber is resistant to high temperature, oil and chemical corrosion.

  Fluorine rubber 23, commonly known as No. 1 rubber in China, is a copolymer of vinylidene fluoride and chlorotrifluoroethylene.

  Fluorine rubber 26, commonly known as No. 2 rubber in China, DuPont brand VITON A, is a copolymer of vinylidene fluoride and hexafluoropropylene, and its comprehensive performance is better than No. 1 rubber.

  Fluorine rubber 246, commonly known as No. 3 rubber in China, DuPont brand VITON B, is a terpolymer of vinylidene fluoride, tetrafluoroethylene, and hexafluoropropylene. The fluorine content is higher than that of 26 rubber, and it has good solvent resistance.

  Fluorine rubber TP, commonly known as tetrapropylene rubber in China, and AFLAS brand of Asahi Glass, is a copolymer of tetrafluoroethylene and hydrocarbon propylene, which has excellent water vapor resistance and alkali resistance.

  Vinylidene fluoride rubber, DuPont brand VITON GLT, is a tetrapolymer copolymer of vinylidene fluoride, tetrafluoroethylene, perfluoromethyl vinyl ether, and vulcanization point monomer, with excellent low temperature performance.

  Perfluoroether rubber, DuPont brand KALREZ, has excellent low temperature performance, high fluorine content, and excellent solvent resistance.

  Fluorosilicone rubber, excellent low temperature performance, has a certain solvent resistance Fluororubber varieties:

  The main varieties of fluorine rubber are: fluorine rubber round strips, fluorine rubber round tubes, fluorine rubber square bars, fluorine rubber special-shaped strips, fluorine rubber sheets, etc.
 

  Fluorine rubber characteristics:
 

  Fluoroplastic is white or amber translucent sheet-like elastomer, non-toxic, odorless, non-flammable (self-extinguishing), has excellent heat resistance, oil resistance, chemical resistance, good physical and mechanical properties and weather resistance, and can be melted in Low molecular weight ketones and lipids.
