PROBLEM TO BE SOLVED: To obtain a heat shrinkage tube capable of drawing in high magnification such as fourfold-drawing. SOLUTION: This heat shrinkage tube is prepared by drawing a tube in high magnification which comprises a composition blending 100 pts.wt of a ethylene-α-olefin copolymer allowed to react using a single site catalyst with at least 100-400 pts.wt of an inorganic filler, a carbon black of less than 70 pts.wt. and a softener of less than 100 pts.wt. By blending as the above composition, it is possible to draw in high magnification. |
