<p>PROBLEM TO BE SOLVED: To prevent a condom from being easily pulled out during use by manufacturing the condom based on a composition obtained by mixing a styrene- ethylene-butylene-styrene copolymer and a specific plasticizer so as to improve the extensibility of the condom. SOLUTION: This condom 10 is manufactured based on the composition obtained by mixing the styrene-ethylene-butylene-styrene copolymer(SEBS polymer) and the specific plasticizer. The used composition obtained by mixing the SEBS polymer and the specific plasticizer is excellent in tensile breaking extension and tensile breaking strength. Consequently, as is highly extensible, flexible and adhesive, the condom 10 is difficult to be pulled out during using and is easy to detach after using. The plasticizer to be used is desirably paraffin or naphthene. Then, the condom 10 is desirably provided with a glans housing part 12 housing the glans of penis and a cylindrical part 14 one tip of which is connected to the housing part 12 and the length of the part 14 is shorter than that of the part 12.</p> |
