20150232586 | CROSSLINKED POLYETHYLENE COMPOSITION - A crosslinked polyethylene composition comprising 100 parts by weight of polyethylene, 0.05-5 parts by weight of crosslinking agent, 0.03-3 parts by weight of crosslinking aid. Polyethylene is a copolymer, homopolymer and/or a mixture thereof. The crosslinking agent is an organic peroxide having a half-life period longer than 3 minutes at 190° C. and/or a multi-membered heterocyclic alkane consisting of 3 to 6 carbon atoms and 3 to 6 oxygen atoms and/or a derivative thereof. The crosslinking aid is an organic substance containing allyl, maleimido, (meth)acrylate group and/or a polymer having a vinyl content higher than 50%. Preferably, the crosslinking aid is triallyl isocyanate (TAIC), triallyl cyanurate (TAC) or a mixture thereof. The crosslinked polyethylene composition has a crosslinking efficiency index >1000 Nm/g and a δ torque value >15 Nm at 220° C., and has a high safe processing temperature and long crosslinking delay, and therefore is particularly suitable for rotationally molded products. | 08-20-2015 |
