Rubber o-rings EPDM 70shore-A FDA food grade
Rubber o-rings EPDM 70shore-A FDA food grade
● Generally, EPDM o-rings are known to possess excellent resistance to ozone, sunlight, and weathering, and has very good flexibility at low temperature, good chemical resistance (many dilute acids and alkalis as well as polar solvents), and good electrical insulation property.
● EPDM o-rings may also come in a metal detectable variation while retaining the same qualities as the general EPDM o-ring compound.EPDM o-rings are typically black in color, with a long-lasting shelf life.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) Performs Well In:Alcohols Automotive brake fluid Ketones Dilute acids and alkalis Silicone oils and greases Steam up to 204.4ºC (400ºF) Water Phosphate ester based hydraulic fluids Ozone, aging, and weathering.
● what's more, EPM is a Copolymer of ethylene and propylene. EPDM is a terpolymer of ethylene and propylene with a small amount of a third monomer (usually a diolefin) to permit vulcanization with sulfur.
● Generally Ethylene Propylene Rubber posses excellent resistance to ozone, sunlight and weathering, and has very good flexibility at low temperature, good chemical resistance (many dilute acids, alkalis & polar solvents), and good electrical insulation properties.
● Shore-A: From 30-90 shore-A any color can do.
● SIZE: AS-568 all size.
