PET is a milky white or light yellow highly crystalline polymer with a smooth and glossy surface. Creep resistance, fatigue resistance, abrasion resistance and good dimensional stability, low abrasion and high hardness, with the greatest toughness in thermoplastics: good electrical insulation performance, little influence by temperature, but poor corona resistance. Non-toxic, weather resistance, good chemical stability, low water absorption, weak acid and organic solvent resistance, but not hot water immersion, alkali resistance. PET resin has high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor dimensional stability, brittle crystallization molding, low heat resistance, etc. Improvement by nucleating agents as well as crystallization agents and glass fiber reinforcement

In addition to the nature of PBT, PET has the following characteristics:

1. The thermal deformation temperature and long-term use temperature are the highest in thermoplastic general engineering plastics;

2. The bending strength is 200MPa, the elastic modulus is 4000MPa, the creep resistance and fatigue resistance are also very good, the surface hardness is high, and the mechanical properties are similar to those of thermosetting plastics;

3. As the price of ethylene glycol used in the production of PET is almost half cheaper than that of butylene glycol used in the production of PBT, PET resin and reinforced PET are the lowest prices in engineering plastics and have high cost performance.
