Rubber & Elastomer Material Choices

Ethylene Propylene (EPR or EPDM) is a polymer featuring outstanding properties. It provides superb weather aging and ozone resistance; excellent water and chemical resistance; exceptional resistance to gas permeability and steam aging; and excellent heat resistance (up to 350°F). Ethylene Propylene exhibits poor oil/solvent resistance, but is fairly good with ketones and alcohols. It isn’t recommended for food uses or exposure to aromatic hydrocarbons
