Abstract
A cellular molded article in a mold pattern having a surface skin, which has an excellent releasing property from a metal mold as well as an excellent printing property of a design formed on a surface of the metal mold, and a producing method thereof are provided. The cellular molded article in a mold pattern having the surface skin and a producing method thereof, in which, at least a face of the surface skin material, which contacts the metal mold, is an olefin thermoplastic elastomer sheet which is composed of an olefin resin without containing a polyethylene resin as its matrix, and pre-expanded beads, which are employed for an expansion molding in a mold pattern, are pre-expanded beads of an olefin resin.
Claims8
A producing method of a cellular molded article in a mold pattern having a surface skin is that, after thermoforming of a surface skin material along by a metal mold face of either one of two metal molds which compose a mold pattern, by means of expansion molding in this mold pattern, the above mentioned surface skin material is melt united to one piece with a surface of cellular molded article in the mold pattern to be molded, wherein at least a face of the above mentioned surface skin material, which contacts with a metal mold, is an olefin thermoplastic elastomer sheet which has a domain which contains a polyethylene as its composing raw material resin and is formed by dynamic curing, and a matrix which is composed of an olefin resin without containing a polyethylene, and wherein pre-expanded beads, which are employed for an expansion molding in the mold pattern, are pre-expanded beads of an olefin resin.
