Fluororubber O-ring

Fluororubber (FKM) is a synthetic polymer elastomer with fluorine atoms on the carbon atoms of the main or side chains. Fluorine atoms have strong electronegativity, and their strong electron withdrawing ability can increase the C-C bond energy on polymer molecular chains, making the main valence bond more stable; At the same time, due to the slightly larger volume of fluorine atoms compared to hydrogen atoms, they can form a shielding effect on molecular chains and resist the erosion of external corrosive media. These structural features make them have excellent properties that cannot be compared to other rubbers, such as high temperature resistance, oil resistance, chemical resistance, good physical and mechanical properties, weather resistance, electrical insulation, and radiation resistance. They are mainly used to make rubber products that are resistant to high temperatures, oil resistance, and media
