Title:
HEAT RECOVERY ARTICLE, HEAT RECOVERY ARTICLE MANUFACTURING METHOD, WIRE SPLICE, AND WIRE HARNESS
Document Type and Number:
WIPO Patent Application WO/2016/174961
Kind Code:
A1
Abstract:
Provided is a heat recovery article that is easily manufacturable and has excellent shrinkability at comparatively low temperatures such as between 130°C to 140°C inclusive, said article also being able to effectively suppress ruptures and breakage and having excellent adhesiveness to an object to be covered even when used in a wide range of temperature environments from approximately -60°C to approximately 120°C. This heat recovery article has a cylindrical shape and includes a base layer, wherein the base layer contains a polyolefin resin, the melting peak temperature of the base layer after being heated for 2 minutes at 180°C is between 115°C to 128°C inclusive, the heat of fusion of the total resin constituent is between 80 J/g to 150 J/g inclusive, the storage modulus at 120°C is 4 MPa or more, the gel fraction is between 40 mass% to 80 mass% inclusive, and the storage modulus at 180°C is from 0.5 MPa to less than 3.0 MPa. A mixture of a first polyolefin resin having a melting point between 125°C to 135°C inclusive and a second polyolefin resin having a melting point less than 125°C is preferably used as the polyolefin resin.
