Cure System: Peroxide-Cured
Standard EPDM o-ring compounds are usually sulfur-cured. Sulfur-cured compounds offer better flexible properties but are more prone to hardening and have an inferior compression set with high temperatures.
Peroxide-cured EPDM o-ring compounds have better heat resistance and a lower compression set. It complies with long-time usage, especially for hose systems in the construction industry, but is more expensive and more difficult for production than the sulfur-cured EPDM o-ring compounds.
EPDM O-Ring Temperature Range:
Standard Low Temp: -55°C (-67°F)
Standard High Temp: 125°C (257°F)
