Polyethylene terephthalate (PET), chemical formula (C10H8O4) N, is by dimethyl terephthalate and ethylene glycol ester exchange or to terephthalate and ethylene glycol esterification synthesis of dihydroxyethyl terephthalate, and then the condensation reaction. Is a crystalline saturated polyester, milky white or light yellow, highly crystalline polymer, smooth and shiny surface, is a common resin in life, can be divided into APET, RPET and PETG.

PET is milky white or light yellow polymer for blowing molding, surface smooth and glossy.
PET has good creep resistance, good fatigue resistance, good corrosion resistance, high hardness.
PET electrical Insulating performanc is good.
Non-toxic, good weather resistance, chemical resistance stability, Bibulous rate is low, resistance to dilute acid and organic solvents.
Features:
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.
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.
