Abstract

Ethylene-propylene copolymers (EPDM) are known for a wide range of useful properties. EPDM-based rubbers have weather resistance, resistance to aggressive environments and wide operating temperatures. EPDM-based blends allow to create composite materials such as open-cell polymer foam. Due to their unique composition, open-cell elastomeric foam based on EPDM can have different structures, densities and properties. This paper presents a study of the possibilities of technologies of first-stage and second-stage foaming in vulcanization presses in order to regulate the pore structure of open-cell material based on ethylene-propylene-diene copolymer.
