Unverified该胶带本身不具备粘性，需靠拉伸缠绕后自融粘合，使用时必须在外层再包裹一层PVC电工胶带或其他固定层，否则端头容易松脱92% similarUnverified粘附力与材质厚度是矛盾：PVC/薄膜粘性强但易破，PE厚膜结实但边缘粘附差需借助容器边压紧；追求密封选带自封收纳的滑刀盒款更实用86% similarUnverified自粘绷带主要成分为聚氨酯泡沫或聚酯纤维加乳胶，横向不回缩、纵向可拉伸，拉伸率通常达1.5-2倍，缠绕时保持轻度拉伸即可自然贴合86% similarUnverified胶带越薄拉伸性越好越能贴合异形接头缠绕更服帖，但绝缘厚度和耐磨性下降；厚胶带机械保护强但缠绕棱角处易鼓包84% similarUnverified可重复粘贴的静电贴或微胶贴无残胶但附着力弱，边角易翘且不能长期贴曲面；强力背胶贴牢固防水但一次性，撕除易留胶或掉漆84% similar
