Ethylene Propylene Diene Rubber (EPDM) polymers are fully saturated, non-polar hydrocarbon based elastomers. Their polymer geometry gives them superior compatibility with polar fluids and polar solvents at elevated temperatures. The materials have high chemical resistance, giving long life in polar solvents, hot water and steam. In addition, they are suitable for contact with alkaline cleaning fluids.
All EPDM grades are peroxide cured and contain a very low amount of softeners and process aids. This reduces potential leach out to a minimum, lowering the risk of contamination. They have also been engineered to achieve enhanced chemical and thermal stability along with compliance to a variety of life sciences standards and approvals.
