Effect of carbon black on the cross-linking a polyolefin composition designed for foaming and on the properties of chemically cross-linked and foamed products
C black was added (conc. 0.4-2.8 cg/g) to a blend of low-d. polyethylene and CH(2)=CH(2)/AcOCH=CH(2) copolymer (70:30 by mass) contg. azodi-carbonamide foaming agent, ZnO and an antioxidant, calendered at 110-120 degrees C for 10 min and cured with (PhCMe(2)O)(2) at 173-185 degrees C under shearing in a reometer to det. the vulcanization parameters. The addn. of C black did not result in any substantial change of the vulcanizate properties except for a decrease in the crosslinking degree and apparent d. of the foam.
