EPDM EXTRUSIONS

AN ENGINEERING GUIDE TO ELASTOMER SELECTION

WC-152 EPR./EPDM

  • Common Name: EPR, EPDM, EPT, NORDEL
  • ASTM D-2000 Classification: CA
  • Military: MIL-STD 417 RS
  • Chemical Definition: Ethylene Propylene

WC-152 Ethylene Propylene is a polymer with outstanding properties. It has exceptionally good weather aging and ozone resistance; excellent water and chemical resistance, excellent resistance to gas permeability; and excellent resistance to aging due to exposure to stream; and heat, resistance excellent up to 350°F. EPR will resist oxidation, ozone, acids, alkalis, and hydraulic fluids. It is ideal for applications requiring good electrical resistance. Ethylene Propylene is a polymer where oil and solvent resistance is poor, however, it is fairly good in ketones and alcohols. It is not recommended for food applications or exposure to aromatic hydrocarbons. It is non-blooming, non-conductuv and non-marking.
