Ethylene propylene diene polymethylene rubber composition and process for producing same (EPDM Compositions and Process for Producing Same)

摘要

EPDM, carbon black having a CTAB of 50 to 60 m 2 / g and DBP of 90 to 115 cm3 / 100 g and a foaming agent, and a foamed EPDM containing a similar amount of a conventional carbon black blend for use in UHF microwave curing Discloses a foamable EPDM composition which is advantageous for replacing the composition. It also comprises carbon black having EPDM and CTAB of 50 to 60 m 2 / g and DBP of 90 to 115 cm 3/100 g, EPDM compositions are disclosed which are advantageous because they have lower sponge density and lower sponge compression set than the EPDM compositions comprising the same amount. In addition, the use of the foamed and cured EPDM compositions of the present invention as gaps is disclosed.
