Fluorine rubber (FKM):
Fluorine rubber refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main or side chains. Fluorine rubber is a type of synthetic rubber designed for high-temperature operation, which has excellent chemical resistance, heat resistance, and oil resistance. It can be used for a long time in environments above 200 ° C
Product application:
Due to its characteristics of high temperature resistance, oil resistance, high vacuum resistance, acid and alkali resistance, and resistance to various chemicals, fluororubber has been applied in cutting-edge technologies such as modern aviation, missiles, rockets, space navigation, ships, atomic energy, and industrial fields such as automobiles, shipbuilding, chemistry, petroleum, telecommunications, instruments, and machinery; Such as seals, vacuum molded parts, high-temperature resistant rubber hoses, chemical resistant sealing materials, and automotive fuel resistant sealing materials.
