PROBLEM TO BE SOLVED: To obtain an externally adding type anti-tack agent for a rubber or a thermoplastic elastomer low in hygroscopicity, oil absorbency and volatility excellent in heat resistance by comprising an organic particulate matter having a specific average particle size. SOLUTION: The subject anti-tack agent comprising an organic particulate matter having a specific average particle size <=500μm (e.g. polyethylene or the like) is obtained. The organic particulate matter preferably has melting temperature or softening temperature >=40 deg.C, hardness >=40 deg. (Shore-D hardness). Preferably <=5g/m2 of the anti-tack agent can be coated or added to the surface of an article to be anti-tack processed. |
