Fluororubber is a synthetic polymer elastomer with fluorine atoms on the carbon atoms of the main chain or side chain. The introduction of fluorine atoms gives fluorine rubber the following main properties:
Heat resistance: fluorine rubber has excellent heat resistance, which is better than other synthetic rubber, and can be used for a long time at 250 ° C or even for a short time at 300 ° C.
Oxidation resistance: fluorine rubber has good oxidation resistance, which makes it stable in high temperature environment.
Oil resistance: Fluorine rubber has excellent resistance to various oils, including high temperature fuel oil, sulfur-containing lubricating oil, hydraulic oil, etc.
Corrosion resistance: Fluorine rubber can resist strong acid, strong alkali, concentrated oxidizer and other corrosive media.
Atmospheric aging resistance: Fluorine rubber has excellent weather aging resistance and ozone resistance.
Physical and mechanical properties: fluorine rubber has good physical and mechanical properties, and its tensile strength is large, generally between 10 and 30MPa, while some types of fluorine rubber such as fluorine silicone rubber have low tensile strength, usually between 7 and 10MPa.
Permeability: and vacuum resistance, fluorine rubber permeability is small, so that it has excellent vacuum resistance.
Radiation resistance: The radiation resistance of fluorine rubber is poor, but it does not affect its application in the atomic energy industry.
Electrical properties: fluorine rubber is suitable for low frequency, low voltage occasions, its electrical properties are affected by temperature and filler type and dosage.
Because of these excellent properties, fluorine rubber is widely used in aviation, aerospace, automotive, petroleum, chemical industry and household appliances and other fields
