对弹性塑料,特别是在触觉性能很关键的特定场合对其要求更为严格。在许多用途采用热塑性聚氨酯(TPU)是利用其优良的耐磨性、屈挠性、耐化学药品性及无需增塑剂的特点。为了获得市场所期望的柔软性,通常是需要通过加入增塑剂或通过与其他较软的材料混合来对TPU进行软化,但遗憾的 It is tougher to use on flexible plastics, especially on specific occasions where tactile properties are critical. The use of thermoplastic polyurethane (TPU) in many applications is based on its excellent wear resistance, flexibility, chemical resistance and plasticizer-free characteristics. In order to obtain the desired softness in the marketplace, it is often desirable to soften the TPU by adding plasticizers or by blending with other softer materials, but unfortunately
