TPU|德國(guó)拜耳|3385吹塑級(jí)
TPU作為彈性體是介于橡膠和塑料之間的一種材料，這從它的剛性看出來(lái)，TPU的剛性可由彈性模量來(lái)度量。橡膠的彈性模量通常在1~10Mpa，TPU在10~1000Mpa，塑料（尼龍，ABS，PC，POM）在1000~10000Mpa。TPU的硬度范圍相當(dāng)寬，從Shore A 60~Shore D 80并且在整個(gè)硬度范圍內(nèi)具有高彈性；TPU在很寬的溫度范圍內(nèi)-40~120℃，具有柔性，而不需要增塑劑； TPU對(duì)油類(lèi)（礦物油，動(dòng)植物油脂和潤(rùn)滑油）和許多溶劑有良好的抵抗能力；TPU還有良好的耐天候性，極優(yōu)的耐高能射線性能。眾所周知的耐磨性，抗撕裂性，屈擾強(qiáng)度都是優(yōu)良的；拉伸強(qiáng)度高，伸長(zhǎng)率大，長(zhǎng)期壓縮永久變形率低等都是TPU的顯著優(yōu)點(diǎn)。TPU華韻塑料供應(yīng)商高韌性 擠出級(jí) 吹塑級(jí)TPU德國(guó)拜耳 1960AW 特性：注塑級(jí)，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.
