Ethylene Propylene Rubbers EPM and EPDM

Heat resistance of up to 200°C is achievable for special applications with proper compounding. Processing of this rubber is generally good except for the lack of building tack. This severely limits the use of EPDM in hand lay-up applications such as liners. However, with the use of proper solvents and adhesives this can be alleviated. 

Since EPDM rubber is costly and the price fluctuates widely, high filler and oil loadings are resorted to, to achieve relatively low cost compounds. But these compounds tend to have poor strength and abrasion resistance. High quality stocks, especially those with peroxide cures, are considerably more expensive than NR, BR or SBR stocks. EPDM is used in belts and hoses meant for conveying hot materials because of its excellent heat resistance. Its excellent chemical resistance makes it a preferred rubber for specialty belts, chemical hoses and pump liners.
