Abstract
A cross-linkable polyethylene composition for high frequency welding comprising a copolymer (A) of ethylene, and an -olefin comonomer (A1) with 3 to 12 carbon atoms having a density of from 850 to 970 kg/m3, a terpolymer (B) of ethylene, a polar comonomer (B1) and a cross-linkable comonomer (B2).
Claims16
A cross-linkable polyethylene composition for high frequency welding comprising
- a copolymer (A) of ethylene and an α-olefin comonomer (A1) with 3 to 12 carbon atoms having a density of from 850 to 970 kg/m3, and
- a terpolymer (B) of ethylene, a polar comonomer (B1) and a cross-linkable comonomer (B2)
- wherein the weight ratio of the copolymer (A) to the terpolymer (B) is 55:45 to 75:25, based on the combined weight of (A) and (B).
The cross-linkable polyethylene composition according to any of the preceding claims, wherein the ethylene copolymer (A) has a density in the range from 860 to 930 kg/m3, measured according to ISO 1183-1:2004.
