What is TPU? TPU(Thermoplastic polyurethanes) name is elastomer rubber. It is mainly divided into polyester type and polyether type, its hardness range is wide (60HA-85HD), wear resistance, oil resistance, transparent, good elasticity, in daily necessities, sports goods, toys, decorative materials and other fields are widely used, halogen-free flame retardant TPU can also replace soft PVC to meet more and more fields of environmental protection requirements. The so-called elastic body refers to the glass transition temperature is lower than the room temperature, elongation at break >50%, the external force removed after the good recovery polymer material. Polyurethane elastomer is a special category of elastomer, polyurethane elastomer hardness range is very wide, performance range is very wide, so polyurethane elastomer is a kind of polymer material between rubber and plastic. It can be heated plasticized and has little or no crosslinking in chemical structure. Its molecules are basically linear, but there is some physical crosslinking. This type of polyurethane is called a TPU. Why filling long glass fiber? Long glass fiber reinforced composites can solve your problems when other methods of reinforced plastics do not provide the performance you need or if you want to replace metal with plastic. Long glass fiber reinforced composites can cost-effectively reduce the cost of goods and effectively improve the mechanical properties of engineering polymers, and increase the durability by forming long fibers to form a long-fiber-reinforced internal skeleton network.
