Thermoplastic co-polyester for production of heat-shrinkable tube and method for producing heat-shrinkable tube by using the same

摘要

The polymerization proceeds to some sort of a thermoplastic polyester copolymer (共 重 合體) in the solid state to increase the intrinsic viscosity to a range of 0.85-1.05 inchi liters / gram and applications for preparing the heat-shrinkable tube. Further, the materials were presented via a heat of fusion of the thermoplastic copolymer in the production method of the kind of the heat-shrinkable tube tubular molding, followed by expansion to the back part way polyester for preparing the heat-shrinkable tube, longitudinal heat shrinkage (MD) of the heat-shrinkable tube is not higher than 15%, chukhyang heat shrinkage (TD) is not lower than 40%. In addition, use of the heat-shrinkable tube is used for covering or outer insulation of the various conductors of the various conductors. ; The thermoplastic, polyester, copolymer, the heat-shrinkable tube,
