    摘要: Incorporation in a thermoplastic resin of a mass of mica flakes having a median shape factor of not less than 0.76, an average particle size of not more than 2,000 .mu.m and an average aspect ratio of not less than 10 followed by molding gives moldings which are high not only in mechanical strength but also in strength at weld parts. Incorporation of said mica flake mass in a thermosetting resin followed by molding affords moldings very high in strength as well as in modulus of elasticity.

    摘要: A diaphragm for an electro-acoustic transducer comprising a sheet formed from a mixture of a polymer and mica, where the sheet contains (a) 30 to 95% by weight of a polymer selected from among polyolefins, polyesters, and polyamides and (b) 5 to 70% by weight of mica having a weight-average flake diameter not exceeding 500 microns and a weight-average aspect ratio of at least 10. By adding the specified mica, the sheet has a drastically improved dynamic modulus and a substantially unchanged loss tangent.
