75 EPDM 295 / 70 EPDM 253815
Ethylene propylene diene monomer rubber
75 EPDM 295 / 70 EPDM 253815 is a rubber based on ethylene and propylene.
- 295: carbon filled, black
- 253815: mineral filled, white
Specially developed for Hygienic USIT® seal and shim washers.
Hygienic USIT® sealing washers are used specifically in systems of the food, beverage and pharmaceutical industries.
They are particularly resistant to hydrolysis and all common cleaning agents used in these areas.
