EPDM Gasket & Seal Material

EPDM (ethylene-propylene-diene-monomer) has excellent resistance to ozone, sunlight, severe weather conditions, oxygen, acids, alkalis, ketones, and aging; outstanding color stability, odor-free characteristics, high heat resistance and dielectric qualities.  All of this makes it ideal for outdoor applications and as a general purpose gasket material for air, hot and cold water, saturated steam.  EPDM rubber gasket material is used for parts in the appliance industry; as low pressure boiler gaskets; weather stripping, boots, dust covers, sleeves, mounts.   It has a poor resistance to fuels and oils.
