HEAT-BONDABLE POLYURETHANE FILM |
摘要 |
<p>The invention aims at providing a polyurethane film which exhibit heat bondability and which has high stress retention and is excellent in elasticity. The invention relates to a heat -bondable polyurethane film characterized by exhibiting both a heat-bond peeling stress of 5.88N/cm or above in terms of the maximum stress as determined by hot-pressing the polyurethane film to cotton cloth at 130°C under a pressure of 4bar for 25 seconds and then peeling the film from the cotton cloth and a stress retention at 200% elongation of 40% or above in the S-S curve observed in the recovery after stretching to 300% elongation in terms of the ratio of stress (f) at 200% elongation in the recovery to stress (f) at the stretching.</p> |
