Freudenberg Sealing Technologies 70 EPDM 253815 Rubber
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	EPDM 253815 White was developed for the process industry. EPDM enjoys high acceptance in the food and pharmaceutical industries. EPDM is indispensable for CIP (clean in place) or SIP (sterilization in place) cleaning processes. However, the fat content of the media may not exceed certain limits. EPDM is a polymerization made of ethylene, propylene and a diene monomer. It displays high media resistance to brake fluids, acids and lyes, the flame-resistant hydraulic fluids HFC and HFD, hot water and steam. But it is not stable in petroleum-based oils and fats or in gasoline and hydrocarbons. In turn, this material is inexpensive and can be used almost universally – although not with oils.
