EPDM Washers

Product Description

Type Physical Properties of CORROSHIELD Black/Grey EPDM Washers

EPDM is cross-linked copolymer consisting of ethylene, propylene and proportion of Diane. This elastomer is particularly characterized by very good ageing and atmosphere resistance. EPDM is stable in: Hot water, steam, suds, ketones, hydraulic fluids from the HFC group which have poor flammability and few HFD types, acids, bases, glycol-based brake fluids, cooling water fluids (water ethylene glycol), ozone, skydol 500 and 700 (phosphate ester fluid).
