Document Type and Number:
Japanese Patent JP2021020426
Kind Code:
A
Abstract:
To solve the problem in which, in the past, a resin member equipped with a base material and a resin molded body formed mainly from ethylene-vinyl acetate copolymer resin and carbon black, which is provided on the base material, may peel off at an interface between the base material and the resin molded body in an environment where the temperature rises to about 80[°C].SOLUTION: A resin member 10 includes a base material 1 and a resin molded body 2 formed mainly from ethylene-vinyl acetate copolymer resin and carbon black provided on the base material 1. The resin molded body 2 has two or more peaks in a range of 25[°C] or higher and 80[°C] or lower in an endothermic curve obtained by measuring the temperature from 25[°C] to 150[°C] by a differential scanning calorimeter (DSC) by increasing the temperature at 5[°C/min].SELECTED DRAWING: Figure 1
