Fluoroelastomer is a copolymer composed of tetrafluoroethylene and perfluoroalkyl vinyl ether or perfluoromethyl vinyl ether monomer.

It has the most comprehensive chemical resistance and can resist the corrosion of more than 1,800 chemicals, including Organic oxides, inorganic oxides, organic acids, inorganic acids, strong acids, strong bases, ketones, esters, alcohols, ammonia, water vapor, and high-temperature water.

Their excellent properties help maintain the integrity of the seal and reduce Repair times and improve safety.

FKM / Fluororubber features: 

• Excellent chemical resistance, solvent resistance, plasma resistance, suitable for chemical equipment and analytical instruments;
• Excellent tensile strength and formability, contribute to improving yield;
• Excellent high and low temperature resistance, the maximum operating temperature can reach 325℃, and the low temperature brittleness can reach -40℃;
• It helps to reduce pollution in the semiconductor manufacturing process, because it produces less particles and low precipitates, and is resistant to alleviation in the plasma environment.
• It can show low outgassing in vacuum sealing applications;
• The volume swelling resistance of nitrous oxide is controlled at about 10%.
