Peroxide cured EPDM | Rubber Technology
EPDM can be cured with sulphur and peroxide, depending on the requirements of the application. Compared with sulphur cured EPDM, peroxide cured EPDM compounds have a better chemical and thermal resistance. Where peroxide cured EPDM can resist a temperature up to 150 C (300 F), sulphur cured EPDM can only resist temperatures up to 120 C (250 F).

Ethylene Propylene / EPM, EPDM
EPM rubber can only be cured using free-radicals (peroxide or radiation curing). As the polymer chains of both EPM and EPDM have completely saturated hydrocarbon backbones, excellent ozone resistance and very good resistance to heat and oxidation are achieved.

Palys presented a paper at the IEC on Luperox AIR-XL technology. The great advantage to Luperox AIR-XL is in auto weatherseal profiles, according to Palys. "Sulfur is able to cure in hot air tunnels, but not conventional peroxides," he said. "Peroxide interferes with the weatherseal surface, so you get a sticky surface."
