College of Engineering, Ahmedabad-380015, [email protected] Example: *Super Set Form (High restoring force EPDM sponge) *Ultra Foaming (Super low specific gravity EPDM or NBR sponge) and more. A pre-formed rubber compound is pressed between heated mould plates with product forming cavities. According to ASTM method D 3182. To determine exactly how chloramine would affect rubber components, the American Water Works Association Research Foundation studied seven basic elastomer formulations (Natural Rubber, Nitrile, SBR, Neoprene, EPDM, Silicone, and Fluorocarbon) and subjected them to a series of tests to examine their life cycle when exposed to chloramine. conductivity imparted to the rubber compound. If you need properties that are slightly different than the ones listed below, we can compound the formulation of the rubber material so that the Viton® rubber specifications suit your needs. EPDM Rubber compounds are type of thermoplastic elastomer having excellent resistance to heat and sunlight also good resistance to alkalis.
