PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, abrasion resistance, good dimensional stability, low abrasion and high hardness, with the greatest toughness among thermoplastics: good electrical insulation, low temperature influence, but poor corona resistance. It is non-toxic, weather resistant, chemical resistant, low water absorption, resistant to weak acids and organic solvents, but not immersed in hot water and alkali. PET resin has a high glass transition temperature, slow crystallization speed, long molding cycle, long molding cycle, large molding shrinkage, poor dimensional stability, crystallization molding is brittle, and low heat resistance. Through the improvement of nucleating agent and crystallization agent and glass fiber reinforcement,
In addition to the properties of PBT, PET has the following characteristics:
1. The heat distortion temperature and long-term use temperature are the highest among thermoplastic general engineering plastics;
2. The bending strength is 200MPa, the elastic modulus reaches 4000MPa, the creep and fatigue resistance are also very good, the surface hardness is high, and the mechanical properties are similar to those of thermosetting plastics;
3. Since the ethylene glycol used in the production of PET is almost half the price of the butylene glycol used in the production of PBT, PET resin and reinforced PET are the cheapest among engineering plastics and have a high cost performance.
application
PET is mainly used for fibers, and a small amount is used for films and engineering plastics. PET fiber is mainly used in the textile industry. PET film is mainly used for electrical insulation materials, such as capacitors, cable insulation, printed circuit wiring substrates, and electrode slot insulation. Another application area of PET film is film base and base tape, such as motion picture film, X-ray film, audio tape, electronic computer tape and so on. PET film also uses vacuum aluminum to make metallized films, such as gold and silver wires, micro capacitor films, etc. Another use of PET is blow-molded products, polyester stretch bottles for packaging. Glass fiber reinforced PET is suitable for electrical and electronic and automotive industries. It is used in various coil bobbins, transformers, televisions, tape recorder parts and shells, automotive lamp holders, lampshades, incandescent lamp holders, relays, and rectifiers.
