Abstract

A long moulded plastic product comprises a decorative layer made of a thermoplastic elastomer and is shaped by extrusion moulding, wherein, the decorative layer comprises 2-10 weight part of OBSH radical foaming agent and 3-10 weight part of one or more salts of organic acid which are selected from ascorbic acid salts, acetate, glucoheptonate, glutamate, malate and succinate.

Description

technical field [0001] The present invention relates to a long molded article having on its surface a decorative layer made of a thermoplastic elastomer foam having uniform and fine cell diameters. [0002] Examples of specific applicable fields include long molded products formed by extrusion molding, such as automotive weather strips for sealing gaps between doors, trunk lid opening / closing parts, etc., and vehicle body openings. Background technique [0003] Long molded articles such as weather strips for vehicles are formed by extrusion molding processing. In this case, after materials such as synthetic rubber and thermoplastic elastomer are subjected to extrusion molding processing, for example, the synthetic rubber is vulcanized in a vulcanizing device to obtain a long molded article. The long molded product is cut to a predetermined size, and then, using a mold, corner portions and the like of the cut molded product are subjected to molding processing to obtain a pro...
