What is FKM diaphragm?

FKM diaphragm

FKM is the abbreviation of fluorine rubber. Fluorine rubber is heat-resistant and chemical-resistant, and its quality is higher than that of nitrile rubber, so it is also more expensive. Wide range of applications. Fluoroelastomer has high chemical resistance, so compared with EPDM diaphragm, FKM diaphragm has a wider range of applications.

Features

FKM diaphragms are resistant to a wide range of solvents and chemicals. For example: hydrocarbon fatty acids, aromatics and chlorides, acid solutions and alkali solutions containing oxidants, etc.

FKM diaphragms are not recommended for low molecular weight ketones, ethers, esters, amines, ammonia, hydrofluoric acid, chlorosulfonic acid and phosphoric acid hydraulic fluids.
