Shanghai Daoqin Plastics Co., Ltd.

1, crystallization property issues: is PET separation structure 规整, therefore tool has crystallization property, crystallization degree can 达40%. is crystallization temperature degree high but also crystallization speed degree slow, therefore through control process, can made color high transparency 无定形PET材 material. its in crystallization property PET is white semi transparent.

PET chemical structure

2, retardant property 质: PET for oxygen gas and oxidation carbon and other tool has relatively high retardant property can, this is its can used for packaging materials important property 质, ratio used for manufacturing water bottle and PET啤酒 bottle .

full PET材 material made as bottle

3, resistant ring property: is PET in has a large amount of ester 基, therefore PET不 resistant strong/high acid strong/high alkali and water gas. PET in Common property or non property solvent agent in comparison stability. PET（ weather resistance ） in outer 暴露6 year, force property can can maintain value 80%, dimensions stability high. PET吸 water property low （ generally small 于0.6%）.

4, hot property 质: PET melting point 250-260摄氏 degree, use temperature degree is 120-150摄氏 degree, heat deflection temperature (HDT) is 85设施 degree, glass fiber reinforcement rear can improve/increase PET heat deflection temperature (HDT) 达200摄氏 degree above.

5, force property 质: type polymer, but also structure in has rigid property ring, generally lower tool has relatively high tensile strength, can made fiber. PET tool has high tensile strength （约 and aluminum film versus 近, PE film 9倍, PC film 3倍, PA 3倍）, PET tool has good wear resistance and creep resistance.

6, electrical property 质: has property ester 键, resistant electrical relatively 差, normal temperature lower is excellent insulation 体.
