CONSTITUTION:A thermoplastic polyester ressn used as an essential constituent is a resin capable of being formed into a sheet shape, and is preferably PET or PBT. A mica powder can be appropriately selected from a phlogopite powder, a muscovite powder and the like. Since the particle diameter and aspect ratio of the mica powder have effects on the stiffness, heat resistance and shape performance of a polyester resin sheet-shaped body obtained, it is preferable that the mica powder has a weight average particle diameter of 15-500mum and a weight average aspect ratio of at least 10. A conductive layer is preferably is resin layer comprising conductive carbon black as an essential constituent and capable of being adhered to or layered on a sheet comprising the polyester resin and the mica powder, a resin film layer formed by application of a conductive ink, a conductive layer using a metallic foil, or a conductive layer comprising long metallic fibers.

摘要： PURPOSE:To obtain a molded item, which reveals highly improved dynamic performance by a method wherein crystalline thermoplastic resin, which is heated up to and melted at a temperature higher than its melting point, or a composite containing said resin, is supplied between open molds, and the molds are clamped under pressure when the resin is cooled down into the specified temperature range. CONSTITUTION:Crystalline thermoplastic resin, which is heated up to and melted at a temperature higher than its melting point, or a composite containing said resin is supplied to open molds, and the resin is cooled down. The rolling of the resin is objected through the mold clamping under pressure within the temperature range, in which the fluidity of the resin is that shown by the resin at a temperature lower than the peak endothermic temperature of fusion and at the same time higher than the peak exothermic temperature of crystallization in the differential scanning calorimetry. Further, the resin is cooled down to a demoldable temperature in order be released from the mold. The rolling ratio of said resin through the mold clamping under pressure is 2 or more. By crossing the border of said ratio of 2, very remarkable effect develops and the preferable ratio is 3-10. The applicable resin is crystalline thermoplastic resin, and crystalline polyolefin such as polyethylene, polypropylene or the like, polybutylene terephthalate or the like is exampled.
