2.Product Overview

TPU (Thermoplastic Polyurethane) is a high-performance thermoplastic elastomer polymer synthesized by the polymerization reaction of polyols, diisocyanates, and chain extenders such as BDO. Integrating the excellent properties of rubber and engineering plastics, TPU features superior elasticity, outstanding wear resistance, high tensile strength, excellent hydrolysis stability and low-temperature flexibility. It is divided into two mainstream series: polyether-based TPU and polyester-based TPU, covering full Shore A and Shore D hardness ranges. With thermoplastic molding characteristics, it supports injection molding, extrusion, blow molding and calendering processes, widely used in footwear materials, electronic accessories, automotive parts, cable insulation, industrial films and sealing components, serving as the most versatile high-end elastomer material in modern polymer industries.

4.Physical & Chemical Properties

Physical Properties

TPU appears as uniform smooth granules at room temperature with good fluidity and excellent thermoplastic processing performance. Polyether-based TPU features outstanding hydrolysis resistance, low-temperature toughness and microbial corrosion resistance, while polyester-based TPU delivers higher mechanical strength, wear resistance and oil resistance. All series of TPU have high elastic recovery rate, soft and smooth surface, no deformation after repeated stretching and extrusion. The material has stable physical properties, uniform particle size, no agglomeration, and adapts to various high-speed automated molding equipment with high molding efficiency and low defective rate.

Chemical Properties

TPU is formed by regular cross-linking polymerization of polyol soft segments and isocyanate hard segments, with stable molecular structure and excellent chemical inertness. It shows strong resistance to oil, grease, solvent, acid and alkali corrosion, and is not easily eroded by sweat, seawater and daily chemical products. The material has excellent anti-oxidation and anti-aging performance, maintaining stable mechanical properties in long-term high-temperature, humid and outdoor environments. It features reliable thermal stability, no decomposition or performance attenuation during conventional plasticizing and molding processes, and supports secondary recycling processing.
