Abstract
A resin member includes a base material and a resin molded body disposed on the base material, the resin molded body containing a main component constituted by an ethylene-vinyl acetate copolymer resin and a carbon black. The resin molded body has two or more peaks within a range of 25° C. to 80° C. in an endothermic curve obtained through measurement performed by heating from 25° C. to 150° C. at 5° C./min with a differential scanning calorimetry (DSC) apparatus.
Claims7
A resin member comprising:
- a polystyrene resin base material;
- and
- a resin molded body disposed on the polystyrene resin base material, the resin molded body containing a main component constituted by an ethylene-vinyl acetate copolymer resin and a carbon black,
- wherein a content of the carbon black is within a range of 15 parts by mass to 50 parts by mass with respect to 100 parts by mass of the resin molded body,
- wherein a thickness of the resin molded body is within a range of 30 μm to 1000 μm, and
- wherein the resin molded body has two or more peaks within a range of 25° C. to 80° C. in an endothermic curve obtained through measurement performed by heating from 25° C. to 150° C. at 5° C./min with a differential scanning calorimetry apparatus.
