General |
FKM is a M Class Rubber
Contains a saturated chain of the polymethylene type Fluoro rubber of the polymethylene type having substituent fluoro and perfluoroalkyl groups on the polymer chain Fluorocarbon elastomers are inherently compatible with a broad spectrum of chemicals. Because of this extensive chemical compatibility, which spans considerable concentration and temperature ranges, fluorocarbons have gained wide acceptance as a material of construction for butterfly valve o-rings and seats. Excellent resistance to mineral acids, salts solutions, oils and many aliphatic and aromatic hydrocarbons. Attacked by caustic (sodium hydroxide) and low molecular weight organics. There are several different grades of material available. Care should be taken in selecting the right grade for the application. |
