Description / Abstract:
This specifications covers the materials and performance of
Ethylene Propylene Diene Monomer (EPDM) sealings in the cooling
circuit. EPDM rubber is a terpolymer of Ethylene, Propylene and
Diene monomers.
Material Description. Materials covered by this specification are divided into six (6) EPDM "Types":
Note: Continuous and Excursion temperature limits are as defined by the Vehicle Technical Specifications (VTS).
•Type A: EPDM for sealing radiator, sulfur cured; -35 °C to +125 °C continuous, +150 °C excursion.
•Type B: EPDM for sealing radiator, peroxide cured; -35 °C to +150 °C continuous, +175 °C excursion.
•Type C: EPDM for sealing in engine applications, peroxide cured, better compression set; -35 °C to +150 °C continuous, +175 °C excursion.
•Type D: EPDM O-rings in water circuit, sulfur cured; -35 °C to +125 °C continuous, +150 °C excursion.
•Type E: EPDM for gasket, peroxide cured, with a functional temperature range of -35 °C to +135 °C. The limits are defined by ASTM D1329 TR10 and the continuous upper limit by SAE J2236.
• Type F: EPDM for gasket, peroxide cured, with a functional temperature range of -35 °C to +150 °C. The limits are defined by ASTM D1329 TR10 and the continuous upper limit by SAE J2236.
