| 摘要 |
The present invention provides a thermoplastic resin structure which has a three-layer structure of flexible skin layer/flexible foamed material layer/hard substrate layer wherein each of the layers comprises a thermoplastic resin capable of melt-adhesion with each other, and the flexible foamed material layer is formed by the injection foam molding method. The resin structure exhibits the capability of being easily recycled and, at the same time, can be produced at a low cost, which has not been achieved by a conventional structure using a cross-linked foamed sheet or a urethane foam, while maintaining the performance in appearance, cushioning, rigidity and the like, and thus markedly useful for application fields requiring high performance in cushioning, sound absorption, heat insulation and the like in automobiles, household electrical appliances, general industrial parts and the like.
