Abstract
PURPOSE: The titled composition with excellent tree resistance suitably used for a power cable, which is prepared by the addition of polybutene-1 and a curing agent- free epoxy resin to a polyolefin.
CONSTITUTION: 1W25pts.wt. Polybutene-1 of MI 0.8W4 and 0.05W7pts.wt. curing agent free epoxy resin are added to and kneaded with 100pts.wt. polyolefin such as PE or PP.
EFFECT: It is possible to prevent deterioration due to water tree even in the presence of a void or foreign substance in an insulator, by forming an insulating layer by applying the composition directly or across a barrier layer to a conductive body.
