PURPOSE:To obtain a resin composition which can give a molding improved in surface hardness, mechanical strengths, rigidity, etc., by mixing a thermo plastic resin with a glass filler and whiskers of a specified diameter in a speci fied ratio. CONSTITUTION:A resin composition is produced by mixing 100 pts.wt. thermoplastic resin (A) (e.g. polyethylene or polypropylene) with 3-100 pts.wt. glass filler (B) (e.g. glass fibers or beads) and 5-50 pts.wt. whiskers (C) of an average diameter of 3mum or below (e.g. aluminum borate whiskers or titanium diborate whiskers). Components B and C may be subjected to surface treatment with a silane coupling agent or the like in order to improve their affinity for component A, and may be subjected to binding treatment with an acrylic resin or the like in order to improve their handleability. A molding obtained from this composition is excellent in surface hardness, so that it can resist scratching in use and can be desirably used as a component of an electrical appliance or the like. |
