La structure moléculaire du plastique PET est hautement symétrique et possède une certaine capacité d'orientation des cristaux, ce qui lui confère des propriétés de formation de film et des propriétés élevées. Le plastique PET possède de bonnes propriétés optiques et une bonne résistance aux intempéries, et le plastique PET amorphe possède une bonne transparence optique. ¡¡¡¡En outre, le plastique PET présente une excellente résistance à l'abrasion, une bonne stabilité dimensionnelle et une bonne isolation électrique. Les bouteilles [...]
Lire la suiteIn addition to the properties of PBT, PET has the following characteristics: 1. The heat distortion temperature and long-term use temperature are very high among thermoplastic general engineering plastics; 2. Because of the high heat resistance, the reinforced PET is immersed in a solder bath at 250°C for 10 seconds, and it hardly deforms or […]
