摘要:
A process for manufacturing a multilayer article, the article comprising two crosslinked semiconductive layers separated by and bonded to an insulation layer, the semiconductive layers formed from a peroxide-crosslinkable olefin elastomer and the insulation layer comprising composition comprising a silane-grafted olefinic elastomer, the process comprises the steps of: (A) injecting the silane-grafted olefinic elastomer between the two crosslinked semiconductive layers so as to have direct contact with each semiconductive layer, and (B) crosslinking the silane-grafted olefinic elastomer in the absence of a peroxide catalyst.
摘要:
Thiobis phenolic antioxidants are efficiently dry or melt blended with a tree-resistant, crosslinkable polyethylene by first forming a blend, preferably a dry blend, of the antioxidant with a polyalkylene glycol (PAG), and then mixing the blend with the polyethylene. The incorporation of thiobis phenolic antioxidant and PAG blend into polyethylene provides the PE with high oxidative induction time (OIT) which is a measure of the oxidative stability of the PE.

摘要:
This invention relates to a flame-retardant composition useful for preparing a coated automotive wire with high scrape abrasion resistance and flexibility. The present invention is a halogen-free, flame-retardant composition made from or containing an ethylene/alpha-olefin copolymer, a halogen-free inorganic flame retardant, a coupling agent for coupling the inorganic flame retardant to the copolymer, and a processing aid.
