Chemours Viton® ETP-500 Fluoroelastomer (FKM)
Material Notes:  Outstanding Fluid/Chemical Resistance - including Ketones, Caustics, Amines

Temperature of Retraction (TR-10): -11°C. Polymer Fluorine Content: 67%. Volume Increase After 7 Days/Methanol/23°C: 10 to 15%

Viton® Extreme™ is made with ethylene, tetrafluoroethylene (TFE), and perfluoromethyl vinyl ether (PMVE). Better resistance to low molecular weight esters, ketones, and aldehydes than standard Viton grades. Inherently resistant to attack by base, and thus provide excellent resistance to volume swell and property loss in highly caustic solutions and amines.

Applications: Transfer-compression molded seals, gaskets
