Fluorine rubber O-ring, corrosion-resistant acid fluorine rubber seals FPM (Fluoro Carbon Rubber) intramolecular fluorine rubber, the fluorine content in accordance with (ie monomeric building) and there are various types. Currently the Department hexafluoride Viton earliest widely used by the DuPont Viton tradename listed. High temperature resistance than silicone rubber, has excellent chemical resistance, resistance to most oils and solvents (ketones, esters excluded), weather resistance and ozone resistance; cold is relatively poor, the general temperature range of -20 ~ 250 ℃. Specially formulated low temperature resistant to -40 ℃.
