TPU颗粒制造商TPU原始颗粒

TPU是一种成熟的环保材料，具有优异的高张力、高张力、强韧性和耐老化性能。目前，TPU已广泛应用于医疗保健、电子电器、工业和体育等领域，它具有其他塑料材料无法比拟的高强度、良好的韧性、耐磨、耐寒、耐油、耐水、耐老化、耐候等性能，同时具有很高的防水透湿、防风、防寒、抗菌、，防霉、保暖、抗紫外线辐射和能量释放等许多优良特性

（1）优异的耐磨性。泰伯的磨损值为0.5-0.35mg，是塑料中最小的。添加二硫化钼和硅油石墨可以降低摩擦系数，提高耐磨性<拉伸强度和伸长率：TPU的拉伸强度是天然橡胶和合成橡胶的2-3倍。聚酯TPU的拉伸强度接近60MPa，伸长率接近410%，而聚醚TPU的拉伸强度为50MPa，伸长率>30%
（3）耐油性和耐汽油性：
TPU的耐油性优于丁腈橡胶
（4）耐低温、耐候和耐臭氧性能
TPU的耐老化性能优于天然橡胶和其他合成橡胶。其耐臭氧和辐射特性在航空航天工业中有着特殊的应用
（5）医疗卫生质量
TPU具有生物相容性和抗凝血性，医用TPU的应用越来越广泛，如人工心脏、人工肾、输血管、血浆袋、输尿管、外科技术固定材料等。
（6）硬度范围
TPU的硬段为肖氏a10肖氏D80，而普通橡胶的硬度范围一般为邵氏A60~100，所有TPU低于邵氏硬度A15的弹性体具有相似的压缩变形特性
肖氏硬度A85及以上时，TPU保持弹性。这是其他弹性体所没有的特性。因此，TPU具有较高的承载能力和良好的减振效果

Product Details

TPU is a mature environmental material with excellent properties of high tension, high tension, strong toughness and aging resistance. At present, the TPU has been widely used and health care, electronic appliances, industrial and sports, etc., it has unmatched by other plastic materials, high strength, good toughness, wear-resisting, cold resistant, oil resistant, water resistant, ageing resistance, weather resistance and other properties, at the same time, he has high waterproof moisture permeability, wind, cold, antibacterial, mouldproof, warm, anti-ultraviolet radiation and energy release many excellent features.

TPU is molecular materials containing – NH – COO – groups, long chain dibasic alcohol and isocyanate component constitutes the soft segments and short key dibasic alcohol and isocyanate component constitutes the hard segment, TPU many features depends on the types of long chain dibasic alcohol, its hardness is the use of hard segment in proportion to adjust, the TPU elastic tape it light aging additive light stabilizer to improve, but also depending on aromatic and aliphatic isocyanate is. It differs from other thermoplastic elasticity in the following excellent properties:

(1) excellent wear resistance. The Taber’s wear value is 0.5-0.35mg, which is the smallest in plastics. If MoS2 and silicon oil graphite are added, the friction coefficient can be reduced and the wear resistance can be improved.
(2) tensile strength and elongation:
The tensile strength of TPU is 2-3 times that of natural rubber and synthetic rubber. The tensile strength of polyester TPU is nearly 60MPa and the elongation is nearly 410%, while that of polyether TPU is 50MPa and >30%.
(3) oil and gasoline resistance:
The oil resistance of TPU is better than that of nitrile butadiene rubber.
(4) low temperature resistance, weather resistance and ozone resistance
The aging resistance of TPU is better than that of natural rubber and other synthetic rubber. Its ozone – and radiation-resistant characteristics have particular applications in the aerospace industry.
(5) medical and sanitary quality
TPU is biocompatible and anticoagulant, and medical TPU has been applied more and more widely, such as artificial heart, artificial kidney, blood transfusion tube, plasma bag, ureter, fixed material for surgical technology, etc.
(6) hardness range
The hard section of TPU is shaw’s a10-shaw’s D80, while the hardness range of ordinary rubber is generally shaw’s A60~100, and all elastomers with TPU under shaw’s hardness A15 have similar compression deformation characteristics.
TPU remains elastic when shore hardness A85 and above 85. This is a property that no other elastomer has. Therefore, TPU has high load supporting capacity and good vibration absorption effect.
