TPU|德国拜耳|3385吹塑级

TPU作为弹性体是介于橡胶和塑料之间的一种材料，这从它的刚性看出来，TPU的刚性可由弹性模量来度量。橡胶的弹性模量通常在1~10Mpa，TPU在10~1000Mpa，塑料（尼龙，ABS，PC，POM）在1000~10000Mpa。TPU的硬度范围相当宽，从Shore A 60~Shore D 80并且在整个硬度范围内具有高弹性；TPU在很宽的温度范围内-40~120℃，具有柔性，而不需要增塑剂； TPU对油类（矿物油，动植物油脂和润滑油）和许多溶剂有良好的抵抗能力；TPU还有良好的耐天候性，极优的耐高能射线性能。众所周知的耐磨性，抗撕裂性，屈扰强度都是优良的；拉伸强度高，伸长率大，长期压缩永久变形率低等都是TPU的显著优点。TPU华韵塑料供应商高韧性 挤出级 吹塑级TPU德国拜耳 1960AW 特性：注塑级，良好的耐磨性；

Polyurethane TPU properties introduced here include three aspects: Mechanical Properties, Physical Properties and environmental properties; 1. Mechanical Properties: TPU Elastomer Mechanical Properties mainly include: Hardness, tensile strength, compression properties, tear strength, resilience and wear resistance, 

flexure resistance, and so on, while elastic plastic TPU mechanical properties, in addition to these properties, there are higher shear strength and impact work. Hardness: Hardness is an indicator of a material's ability to resist deformations, Nicks, and scratches. TPU hardness is usually measured with Shore a and Shore d hardness meters, Shore a for softer TPU, Shore D for harder TPU. Hardness is mainly determined by the hard segment content in TPU structure. The higher the hard segment content, the hardness of TPU will increase. With the increase of hardness, other properties of TPU also changed, tensile Modulus and tear strength increased, rigidity and compressive stress (load capacity) increased, elongation decreased, density and dynamic heat increased, and environmental resistance increased. TPU hardness and temperature have a certain relationship. The hardness of TPU changed little from room temperature to abrupt change temperature (- 4 ~-12 °C) , but it became hard and lost elasticity because of crystallization of soft segment.
