Synthesis and processing of TPU thermoplastic polyurethane elastomer

What is the TPU material? TPU is thermoplastic polyurethane, which is a kind of polyurethane that can be plasticized by heating and dissolved by solvent. Compared with the mixed and cast polyurethane, the chemical structure of thermoplastic polyurethane has no or little chemical crosslinking, its molecules are basically linear, but there is a certain amount of physical exchange. The concept of physical exchange, as it is called, was developed in 1958 by SchollenbergeC. First of all, it is proposed that there is a "connection point" between linear polyurethane molecular chains that is reversible in the presence of heat or solvent, which is not actually chemical crosslinking, but plays the role of chemical crosslinking. Due to this physical crosslinking, polyurethane has formed the theory of polyphase morphology structure. The hydrogen bond of polyurethane strengthens its morphology and makes it withstand higher humidity. According to soft segment structure can be divided into polyester type, polyether type and butadiene type, they contain ester group, ether group or butadiene group respectively. According to the hard segment structure, they can be divided into aminoester type and aminoester urea type, which are obtained from diol chain extender or diamine chain extender, respectively. The common division is polyester type and polyether type. 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 the 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. Performance is preserved in a wide range of environments. TDS for your reference only Application Details Xiamen lft composite plastic Co., Ltd
