Formteil aus Harz und Verfahren zu dessen Herstellung

摘要

A resin molded article is produced by performing extrusion molding of a thermoplastic amorphous resin containing a dispersion phase, and then rolling it. According to a molecular orientation associated with an elongation of the dispersion phase in the rolling direction, it is possible to provide the resin molded article having an increased elastic modulus and a reduced coefficient of linear expansion.
