Viton material properties | Rubber Technology

Viton® material properties: heat resistance. Viton® seals are well known for their excellent heat resistance. ERIKS has been testing the heat resistance at 250°C for 70 hours and the test shows perfect results for Tensile Strength Change, Elongation Change and Hardness Change. We make sure your seals have an optimal life span.

Peroxide cured EPDM | Rubber Technology

The advantages of using peroxides. Peroxides improve the heat stability, the modulus, the aging and the compression set of compounds. In addition the color of the compound will not revert during the cure and has less tendency to bloom. Peroxide cured EPDM is widely used in the rubber industry due to these enhanced properties.

EPDM vs Silicone: a simple guide | Knowledge Center

14/1/2019· EPDM beats SBR in tensile strength and resistance to heat aging and weathering. Nitrile butadiene rubber (NBR): Nitrile is king of elastomers when it comes to oil- and fuel-resistance. One attraction to NBR is its stability in low temperatures, with the ability to survive extreme cold of -30˚C/ -22˚F, which EPDM and Silicone can’t match.
