Effect of foaming temperature on morphology and compressive properties of Ethylene propylene diena monomer rubber (EPDM) foam

The morphology and compressive properties of EPDM foam were investigated against foaming temperatures (i.e 140, 150 and 160 o C). The blowing agent used in this study was sodium bicarbonate. The rubber compositions were expanded and cured using conventional compression moulding technique via heat tr...
