服装弹力带级TPU Shore A 85颗粒

TPU-由含有NCO官能团的MDI和多元醇以及含有OH官能团的1.4BG组成。它是通过揉捏和揉捏制成的。由于其良好的弹性、良好的物理性能和优异的机械强度，被广泛用于注塑和挤出。压延和溶解成溶液树脂的加工方法是塑料加工行业经常使用的塑料材料，其产品涵盖工业应用和人民生活的范围

性能：
1、耐磨性
当材料在使用过程中经常受到摩擦、刮擦和挫折等机械作用时，会导致表面逐渐磨损，因此材料磨损的选择非常重要。TPU塑料原材料具有优异的耐磨性，耐磨性是天然橡胶的五倍以上。它是耐磨产品的首选材料之一
2，拉伸性能
拉伸强度高达70MPa，断裂伸长率高达1000%
3，撕裂性能
当使用弹性体时，裂纹扩展造成的损坏称为撕裂。撕裂强度是材料抵抗撕裂效应的能力；总的来说，TPU具有很高的抗撕裂性和撕裂强度，一些常用的橡胶和塑料相当优异
4，弯曲性能
许多塑料材料在反复循环应力下容易断裂。TPU产品能在不同环境下保持优异的抗断裂性能，是聚合物材料的最佳选择之一

Product Details

Clothing elastic band GRADE TPU Shore A 85 Granules

TPU – It is made of MDI containing NCO functional group and POLYOL and 1.4BG containing OH functional group. It is made by kneading and kneading. Because of its good elasticity, good physical properties and excellent mechanical strength, it is widely used for injection and extrusion. The processing method of calendering and dissolving into a solution resin is a plastic material frequently used by the plastics processing industry, and its products cover the range of industrial applications and people’s livelihoods.

Properties :
1, wear resistance
When the material is often subjected to mechanical action such as friction, scraping, and frustration during use, it will cause the surface to wear gradually, so the choice of material wear is very important. TPU plastic raw materials have excellent wear resistance and are more than five times more wear-resistant than natural rubber. It is one of the preferred materials for wear-resistant products.
2, tensile properties
The tensile strength is up to 70 MPa and the elongation at break can be as high as 1000%.
3, tear performance
When the elastomer is applied, the damage caused by the expansion of the crack is called tearing. The tear strength is the ability of the material to resist the tearing effect; in general, the TPU has high tear resistance, tear strength and some commonly used Rubber and plastic are quite excellent.
4, inflection performance
Many plastic materials are prone to breakage under repeated cyclic stresses. TPU products can maintain excellent fracture resistance under different environments and are one of the best choices for polymer materials.
