In 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 […]
