Abstract

PURPOSE:Title resin composition that contains a specific amount of granular inorganic fillers, thus being suitably used for the drum material of VTR, headmold material, tape guide material, etc., because of its freeness of anisotropy caused by orientation, high dimensional accuracy in molding and high mechanical strength. CONSTITUTION:To (A) an unsaturated polyester resin [a condensate of alpha,beta- ethylenically unsaturated dicarboxylic acid of its anhydride with polyhydric alcohol or a mixture thereof] is added (B) 40-65vol% of granular inorganic filler as glass beads or calcium carbonate. The component A may contain thermoplastic resin as acrylic resin and the particle size of the component B is 40-50mu when it is glass beads and 1-100mu in calcium carbonate.
