Title:
RESIN COMPOSITION, RESIN COMPOSITION MOLDED BODY, POWER CABLE, AND METHOD FOR MANUFACTURING POWER CABLE
Document Type and Number:
WIPO Patent Application WO/2022/137750
Kind Code:
A1
Abstract:
This resin composition is for covering the exterior of an object having a long length. In a molded body that contains the resin composition which contains a propylene unit which was subjected to a prescribed bending test, there are no voids having a maximum length of 1 μm or greater and there is no crystal having a maximum length of over 10 μm. The bending test includes: a first step for bending a power cable such that the bend ratio, which is the ratio of the bend radius of the power cable to the outer diameter of an insulation layer, is 7 or less; and a second step for bending the power cable to the direction opposite the bending direction of the first step, with the same bend ratio.
