PURPOSE:To obtain the subject composition having a markedly high expanding property by blending a plastisol containing a vinyl chloride-based resin, etc., produced by emulsion polymerization with a specified zinc oxide. CONSTITUTION:To a plastisol containing 100pts.wt. vinyl chloride-based resin produced by emulsion polymerization, preferably 50-80pts.wt. plasticizer (e.g. dioctyl phthalate) and preferably 3-6pts.wt. azodicarbonamide as an expanding agent, zinc oxide having <=0.05mum average particle size and >=25m<2>/g surface area is added preferably in an amount of 1-2pts.wt., thus obtaining the objective composition. |
