Thermoplastic polyester elastomer (TPEE), also known as polyester rubber, is a linear block containing PBT (polybutylene terephthalate) polyester hard segments and aliphatic polyester or polyether soft segments copolymer. thing. TPEE combines the excellent elasticity of rubber with the ease of processing of thermoplastics, with adjustable hardness and freedom of design. It is a new variety of thermoplastic elastomer that has attracted much attention.
In 1972, DuPont of the United States and Toyobo of Japan were the first to develop TPEE, with the trade names Hytrel and Pelprene respectively. Subsequently, major companies in the world such as Hochest-Celanese, GE, Eastman, AKZO (DSM) have successively developed various brands of TPEE products, the trade names are Ritefex, Lomod, Ecdel and Arnitc. Domestic TPEE has also developed its own brand. Nantai brand TPEE developed by Wuhan Southeast Xiangtai Company is also well received in China.
Compared with rubber, thermoplastic polyester elastomer (TPEE) has better processing performance and longer service life; compared with engineering plastics, it also has the characteristics of high strength, good flexibility and good dynamic mechanical properties. For most applications, TPEE can be used directly. If there are special requirements, the corresponding additives can be added to meet the requirements.
