PURPOSE:A vinyl chloride resin composition for vinyl tile, having improved heat resistance, molding and processing characteristics, mold releasability and appearance of stable color tone, obtained by blending vinyl chloride resin with a stabilizer and a lubricant. CONSTITUTION:100pts.wt. vinyl chloride resin is blended with (A) 25-50pts.wt. plasticizer (e.g. phthalic ester plasticizer, etc.), (B) 150-300pts.wt. filler (e.g. calcium carbonate, etc.), (C) 0.5-5pts.wt. tin type stabilizer consisting of C1: 30-95wt% dialkyltin compound shown by formula I (R is 1-8C alkyl; R' is 6-16C alkyl, etc.; m is 1 or 2) and C2: 5-70wt% alkyltin compound shown by formula II, (D) 0.5-5pts.wt. lubricant consisting of D1: 10-100wt% ester of higher fatty acid and higher fatty alcohol and D2: 0-90wt% higher fatty acid and (E) 0.1-5pts.wt.metallic soap stabilizer consisting of E1: 50-100wt% higher fatty acid calcium salt and/or barium salt and E2: 0-50wt% higher fatty acid zinc salt.
