This is because ozone and UV rays arent able to break up its molecular structure in the same way as rubbers with double bonds. We have found an existing account with credentials. [4], EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers having a saturated chain of the polyethylene type (the M deriving from the more correct term polymethylene). It is also used for cushioned edge guards and bumpers on appliances, equipment, and machinery. However, they are not compatible with mineral and synthetic di-ester lubricants, and hydrocarbon fuels and solvents. EPDM seals can be a source of squeaking noise, due to the movement of the seal against the opposing surface (and its attendant friction). As with most rubbers, EPDM is always used compounded with fillers such as carbon black and calcium carbonate, with plasticisers such as paraffinic oils, and has useful rubbery properties only when crosslinked. No. 045 mil to .090 mil, can be reinforced or non-reinforced, and is typically black in color, but can be white..
