75 EPDM 295 / 70 EPDM 253815
Ethylene propylene diene monomer rubber
75 EPDM 295 / 70 EPDM 253815 is an ethylene and propylene based rubber.
291: Soot filled, black
253815: Mineral filled, white
It was developed especially for the Hygienic USIT® sealing and shim washers.
Hygienic USIT® sealing washers are specially designed for use in the foodstuff, beverage and pharmaceutical industries.
They are particularly resistant to hydrolysis and all common cleaning agents used in these sectors.
