| 摘要 |
This pressure-sensitive adhesive sheet of improved conformability and splitting resistance which may be advantageously employed, for example, as a surgical drape or used in tape form or as part of a surgical bandage comprises a flexible polyurethane foam web which is compressedly set to less than about 50 percent of its original thickness and has a splitting resistance of at least about 20 pounds per square inch, an extent of elasticity of at least about 110 percent and a 100 percent modulus of less than about 5 pounds per inch width. A porous pressure-sensitive adhesive is applied to at least portions of one side of the web and, in certain embodiments, a low-friction coating is applied to the other side. In other embodiments, a release coating which may also have a low coefficient of friction may be applied to enhance unwindability. As a tape, the product is advantageously applied to irregularly shaped portions of the body having varied and changeable conformability requirements, such as joint locations, particularly knuckles, elbows, knees and the like. |
