TPU材料是介于橡胶和塑料的一类高分子材料，其材料叫做热塑性聚氨酯弹性体橡胶。主要分为聚酯型和聚醚型，它硬度范围宽(60HA-85HD)、耐磨、耐油，透明，弹性好，在日用品、体育用品、玩具、装饰材料等领域得到广泛应用，无卤阻燃TPU还可以代替软质PVC以满足越来越多领域的环保要求。

TPU材料为聚合型热塑性弹性体。对于TPU的聚合反应及相关单体，TPU是由二苯甲烷二异氰酸酯(MDI)或甲苯二异氰酸酯(TDI)等二异氰酸酯类分子和大分子多元醇、低分子多元醇(扩链剂)共同反应聚合而成的高分子材料。它的分子结构是由二苯甲烷二异氰酸酯(MDI)或甲苯二异氰酸酯(TDI)和扩链剂反应得到的刚性嵌段以及二苯甲烷二异氰酸酯(MDI)或甲苯二异氰酸酯(TDI)等二异氰酸酯分子和大分子多元醇反应得到的柔性链段交替构成的。

TPU是一种成熟的环保材料，具有高张力、高张力、韧性和耐老化的优良特性。TPU已广泛应用于电子电器、工业和体育等领域。它具有强度高、韧性好、耐磨、耐寒、耐油、耐水、耐老化、耐候等特点。这是其他塑料材料无法比拟的。同时具有高防水透湿、抗风、防寒、抗菌、防霉、保暖、抗紫外线、释放能量等诸多优异功能。

热塑性聚氨酯弹性体橡胶(TPU)的主要特点是硬度范围广，通过改变TPU的各种反应组分的比例，可以得到不同硬度的产品，并且随着硬度的增加，产品仍然保持良好的弹性和耐磨性。ta:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAA4AAAAOCAYAAAAfSC3RAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAAyJpVFh0WE1MOmNvbS5hZG9iZS54bXAAAAAAADw/eHBhY2tldCBiZWdpbj0i77u/IiBpZD0iVzVNME1wQ2VoaUh6cmVTek5UY3prYzlkIj8+IDx4OnhtcG1ldGEgeG1sbnM6eD0iYWRvYmU6bnM6bWV0YS8iIHg6eG1wdGs9IkFkb2JlIFhNUCBDb3JlIDUuMy1jMDExIDY2LjE0NTY2MSwgMjAxMi8wMi8wNi0xNDo1NjoyNyAgICAgICAgIj4gPHJkZjpSREYgeG1sbnM6cmRmPSJodHRwOi8vd3d3LnczLm9yZy8xOTk5LzAyLzIyLXJkZi1zeW50YXgtbnMjIj4gPHJkZjpEZXNjcmlwdGlvbiByZGY6YWJvdXQ9IiIgeG1sbnM6eG1wPSJodHRwOi8vbnMuYWRvYmUuY29tL3hhcC8xLjAvIiB4bWxuczp4bXBNTT0iaHR0cDovL25zLmFkb2JlLmNvbS94YXAvMS4wL21tLyIgeG1sbnM6c3RSZWY9Imh0dHA6Ly9ucy5hZG9iZS5jb20veGFwLzEuMC9zVHlwZS9SZXNvdXJjZVJlZiMiIHhtcDpDcmVhdG9yVG9vbD0iQWRvYmUgUGhvdG9zaG9wIENTNiAoV2luZG93cykiIHhtcE1NOkluc3RhbmNlSUQ9InhtcC5paWQ6NTBERkMzM0M3MDUxMTFFNzk1NkRCNzg0RkMwMDUzMzkiIHhtcE1NOkRvY3VtZW50SUQ9InhtcC5kaWQ6NTBERkMzM0Q3MDUxMTFFNzk1NkRCNzg0RkMwMDUzMzkiPiA8eG1wTU06RGVyaXZlZEZyb20gc3RSZWY6aW5zdGFuY2VJRD0ieG1wLmlpZDo1MERGQzMzQTcwNTExMUU3OTU2REI3ODRGQzAwNTMzOSIgc3RSZWY6ZG9jdW1lbnRJRD0ieG1wLmRpZDo1MERGQzMzQjcwNTExMUU3OTU2REI3ODRGQzAwNTMzOSIvPiA8L3JkZjpEZXNjcmlwdGlvbj4gPC9yZGY6UkRGPiA8L3g6eG1wbWV0YT4gPD94cGFja2V0IGVuZD0iciI/PjUUOd0AAAKHSURBVHjaVJJdSBRRFMf/d/aOs7szq7huFiuNrLaUkqhkUoJCQR8vgUFZIX08GEiED0H5ID1VEPTxavkkQfaSYCRkEAg+hA9BWGhJoUuirK5K5dbOzM7O6exuPXRh4J4z53fu/f/PFZnnaBUSU+ClKICq5jf4fxHgZoFcjvdCB7mZDmGNgdQari0BPEfDp4SGVOon0pkiE9CAUEhHQ1wgEEqDsm1wvs4ADFreLCj5Nkh3rjdSqHQn96+mQ60ldLTNR0YozHGELp+J0sIkyJsD5ZkCSIugp3eNQkHtrloaG9pHtKQRrUiaGqmh/c1x/mfQ/WvgfBGU/2Soal5YEOsbGays8v2y+ayL9sMJjJtVmJgEDjSx3K1ifV6jpdZC29rSsLCm4c30Dtx67KA6sgSp5CB9Ale7JS72cadl9sHingnYRTAGLe+c4uOkG0QylUH6Nyd8QYxO7ca9wQ+IVkUxNGCh/WAK9izsgvFKGfDslYRo0HCk10COgqhrBOoaXPT3Aj1dZfg8v4rE0nfW9FdbwZwvoLnxMJ07XU/lYT+d3KvT60eCJoYV6jkb4KP9VL8nTu9GI0TzRXOE+xKWjzXOfAQ2vSgeDPuRnFzDsuOi3LAQ4xmbLdvQ1+2hLrYBLw0432BLBQKDT1TcHpRI/XAQKXXg6ApulPpwJeaD0cIvozUFVLAxfLbgUF3fDowMSMuv5ocsSBQeF4g9ohOKoE3FT6Tp5Bp+cpoDlD1mkN3Bs7x0nOTDUYLwHNRUm0wp+MW0uZJEl2NxLJGzMyD2ULwXPNUspB4GKo1OZTlVQecvnJoWPmnqumH6DcPUPc9s6r+5GK6qtG1Gi59jy1i1LeORTsjciz8CDACzHh/U4gnF4AAAAABJRU5ErkJggg==") center center no-repeat; display: inline-block; vertical-align: top;">
