PURPOSE:To obtain the title material having excellent molding precision, heat resistance and dispersibility and capable of directly molding by mixing with 4 resin pellet by blending a surface-treated inorganic filler with a thermoplastic resin at a specific ratio, heating and melting and kneading the blend, cutting the kneaded material into fine grains and solidifying the grains. CONSTITUTION:The objective material obtained by blending 50-90wt.% inorganic filler (e.g. talc, sericite, mica or kaolin) surface-treated with a silane coupling, etc., with 50-10wt.% thermoplastic resin (e.g. PE or PP) at a specific ratio, subjecting the blend to heat melting to knead the blend, cutting the kneaded material into fine grains having <=1mm grain diameter and solidifying the grains. |
