Various types of additives, soap, ester, silicone, perfluorinated, and fatty acid compounds, were compounded into chlorine (soap, ester and silicone) and fluorine (silicone, perfluorinated and fatty acid compounds) elastomer compound. The addition of processing additives into chlorine and fluorine elastomer improves the processability without sacrificing of the physical properties. Depending on the compound formulation and application, some nonperfluorinated additives (carnauba, WB16, WB222, HT290 and WS280) show improved processability in the chlorine and fluorine elastomer compound. In CR compound, the WB16 and WB222 exceed vegetable wax (carnauba) clearly. Comparing perfluorinated and nonperfluorinated additives in FKM compounds, the HT290 and WS280 exceeds or is equal to a perfluorinated additive (PPA790), respectively. A careful adjustment to the compound provides a maximum of overall processing properties, while physical properties remain almost unchanged.
