Cross-linked polyolefin material blend
A material combination that is designed to replace current high-density polyethylene (“HDPE”) materials for use with electrical transmission comprising at least one low density, cross-linkable polymer resin, at least one high density polymer, a cross-linking catalyst and an optional color masterbatch The material combination provides all of the existing properties found in the HDPE material with the addition of a higher temperature capability at/above 250° C.
1. A compound for use in molded electrical transmission products, the compound comprising:
a) at least one low density, cross-linkable polymer resin present at about 53% by weight of the total compound;
b) at least one high density polymer present at about 37% by weight of the total compound;
c) a cross-linking catalyst present at about 5% by weight of the total compound; and
d) a color masterbatch including at least one colorant and at least one stabilizer present at about 5% by weight of the total compound.
2. The compound of claim 1 wherein the at least one low density, cross linkable polymer resin is a ethylene vinylsilane copolymer.
3. The compound of claim 1 wherein the at least one stabilizer is selected from the group consisting of UV stabilizers, anti-oxidants, amine light stabilizers, and track resistance compounds.
4. The compound of claim 1 wherein the at least one high density polymer is a high density polyethylene.
