Material Notes:

Peroxide cured, white Ethylene Propylene Terpolymer, 66-75 °IRHD. Terpolymer of ethylene, propylene and diene monomers. Formulated using only those ingredients determined by the United States Federal Food and Drug Administration (FDA) to be in accordance with Code of Federal Regulations Title (CFR21), Section 177.2600. Extraction tested in distilled water. Also complies with the requirements of USP 25, NF20, 2002, Class 6.Applications: Excellent water and steam resistance with good compression set properties. Heat and chemical resistance is superior to that of sulphur cured EPDM. Not oil resistant.
