PURPOSE:The titled sheet removing skin from the body without pain and to make it beautiful, by blending four ingredients as essential ingredients, a thermoplastic elastomer, tackifier resin, synthetic rubber, and a liquid polymer miscible with these ingredients. CONSTITUTION:100pts.wt. thermoplastic elastomer having a tensile strength preferably at least 10kg/cm<2> and a melt index not less than 200 is blended with 50- 600pts.wt. tickifier resin having a softening point preferably not higher than 180 deg.C, e.g., gum rosin, etc., 2-30pts.wt. syntheric rubber, e.g., butyl rubber, and 30- 200pts.wt. liquid polymer miscible with any of these three ingredients, e.g., polybutene, liquid polyisobutylene, etc. to give a blend consisting of four essential ingredients, and the blend is processed into a sheet or film by well-known means, e.g., extrusion, calendering, flow casting, etc. |
