Abstract
A composition for use in piping and pump systems for elevated temperature, steam and certain chemical resistant applications of ethylene-propylene copolymer with peroxide generated carbon to carbon crosslinkage. Effective amounts of antioxidants, carbon black, lubricant, thermal stabilizer and aid to peroxide crosslinkage is added. An antioxidant and thermal stabilizer system is used to produce a product with unusual thermal stability characteristics. The composition may also have a mixture of high and low particle size carbon black which acts as an antioxidant and reinforcing system. The composition may also use very fine particle carbon black for a highly elastic application. The composition can be used for rubber components which are exposed to a high temperature or to certain chemical environments, or where unusually high elasticity is required.
