Product Description


PET material, commonly known as polyester resin, is the most important variety of thermoplastic polyester. Its physical properties are milky white or light yellow highly crystalline polymer with smooth and shiny surface. Creep resistance, fatigue resistance, abrasion resistance, low wear and high hardness, with the greatest toughness among thermoplastics.

1. Good electrical insulation performance, less affected by temperature, but poor corona resistance.
2. Non-toxic, weather resistance, good stability against chemicals, low water absorption, resistant to weak acids and organic solvents, but not resistant to hot water soaking, not alkali resistant.
3. The glass transition temperature of PET resin is high, the crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate is large, the dimensional stability is poor, the crystallized molding is brittle, and the heat resistance is low.
4. The heat distortion temperature and long-term use temperature are very high among thermoplastic general engineering plastics.
5. 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 and does not change color. It is especially suitable for the preparation of electronic and electrical parts for soldering.
6. The bending strength is 200MPa, the modulus of elasticity reaches 4000MPa, the creep resistance and fatigue resistance are also very good, the surface hardness is high, and the mechanical properties are similar to thermosetting plastics.Application:
1. PET is mainly used for fibers, and a small amount is used for films and engineering plastics.
2. Another use of PET is blow molding products, which are used in various bottles, such as water bottles, carbonated beverage bottles, and oil bottles.
