What happens to EPDM at high temperatures?
Hot. +130°C EPDM starts to degrade. +230°C Silicone starts to degrade.
How much heat can O-rings take?
The general accepted range for o-ring use is approximately -75 degrees and 620 degrees Fahrenheit. This wide spectrum is due to the materials from which o-rings can be manufactured.
What is the difference between Viton and EPDM O-rings?
Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges. Both have different properties and applications for general industrial use.
What is EPDM resistant to?
Because of its excellent resistance to ozone, sunlight and severe weather conditions, EPDM is ideal for outdoor service. EPDM generic temperature range is -50ºC/+150ºC. with continuous operation at 80ºC; intermittent at 100ºC. EPDM has poor resistance to oil, gasoline and hydrocarbon solvents.
What is the temperature rating for EPDM rubber?
EPDM – excellent heat and steam resistance for o-rings Ethylene propylene rubber has a temperature range of -50°C to +120°/150°C (-60°F to +250°/300°F), depending on the curing system.
What material can withstand 300 degrees?
1. Vespel ® Without a doubt Vespel ® can take the heat. This heat resistant, non-melting polyimide can withstand repeated heating up to 300° C without altering its thermal or mechanical properties.
What temp do rubber O-rings melt?

|---|---|---|
| – 30° to 250° | – 34° to 121° | Nitrile (General Service) |
| – 65° to 225° | – 55° to 107° | Nitrile (Low Temperature) |
| – 15° to 500° | – 26° to 260° | Perfluoroelastomer (Parofluor) |
| – 5° to 350° | – 21° to 177° | Polyacrylate |

What is the difference between PTFE and EPDM?
Reduced fouling and cleaning frequency: PTFE membranes can help slow the rate of membrane fouling, often by a factor of five to 10 when compared with EPDM membranes. This advantage occurs because of the nonstick properties of PTFE, which make it hard for organic matter to adhere to and accumulate on the PTFE surface.
What is the difference between EPDM and Buna N?
EPDM (Ethylene Propylene Diene Terpolymer) stretches the upper and lower boundaries for temperature when compared to Buna. EPDM is excellent for hot water and steam service up to 275°F (135°C). EPDM also keeps its flexibility in freezing temperatures (down to -55°F).
Is EPDM compatible with sodium hypochlorite?
How resistant is EPDM? EPDM has good resistance to many chemical products like detergents, caustic potash solutions, sodium hydroxide solutions, and many other diluted acids and chemicals.
What is the temperature range for EPDM O rings?
EPDM O-Ring Temperature Range: Standard Low Temp: -55°C (-67°F) Standard High Temp: 125°C (257°F) SPEC SHEET: Ethylene Propylene Diene Monomer (EPDM) 70 Durometer
What is EPDM O ring material?
EPDM O-Ring Material Description Ethylene Propylene Rubber (EPR) is a Copolymer of ethylene and propylene. Furthermore, EPDM is a terpolymer of ethylene and propylene with a small amount of a third monomer (usually a diene) to permit vulcanization with sulfur.
What is the resistance of EPDM to steam?
Special EPDM compounds have good resistance to steam. EPDM Sulphur cured: inexpensive material for normal use, maximum temperature of +120°C (+250°F). EPDM Peroxide cured: for hot water, steam, alcohols, ketones, engine coolants, organic and inorganic acids and bases. Not resistant to mineral oils, greases and fuels.
What is the temperature range of EPDM/ethylene propylene rubber?
Ethylene propylene rubber has a temperature range of -50°C to +120°/150°C (-60°F to +250°/300°F), depending on the curing system. Special grades can even see higher temperatures. About EPDM / ethylene propylene diene monomer
