德國拜耳TPU Desmopan 359物性表報(bào)價(jià)相關(guān)介紹如下：
Mechanical properties: the mechanical properties of TPU elastomer mainly includes: hardness, tensile strength, compression performance, tear strength, resilience and wear-resisting performance, flexor interference resistance, etc., and the mechanical properties of TPU elastic plastic, in addition to these performance, and higher shear strength and impact energy, etc.
2. Hardness: hardness material deformation resistance, a measure of the ability of the nicks and scratches.TPU hardness usually use Shao Er A (Shore A) and Shao Er D (Shore D) determination of hardness tester, Shao Er used to compare A soft TPU, Shao Er D for harder TPU.Hardness is mainly composed of hard segment content of TPU structure, hard segment content, the higher the TPU hardness will rise.Hardness after rising, TPU other performance will also change, tensile modulus and tear strength increased, and the compression stress (load) increase rigidity, elongation decreased, the density and heat production increases, the dynamic environment resistance increase.There is a certain relationship between hardness and temperature of TPU.Temperature from room temperature cooling to mutation (4 ~ 12 ℃) and hardness has no obvious change;Mutations in temperatures, TPU hardness increases suddenly become very hard and loss of elasticity, this is because the soft segment the results of the crystallization.
