PET is the height of milky white or light yellow crystalline polymer, surface smooth and glossy. Resistance to creep, fatigue resistance, friction resistance and good dimensional stability, wear small, high hardness, has a greater resilience: thermoplastic plastics electric insulation performance is good, affected by temperature is small, but the corona resistance is poor. Non-toxic, good weather resistance, chemical resistance stability, bibulous rate is low, resistance to dilute acid and organic solvents, but not hot water immersion, not alkali resistance. PET resin of high glass transition temperature, crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate, poor dimensional stability, crystallization of forming a brittleness, low heat resistance. Through crystallization nucleating agent and the agent and the improvement of glass fiber reinforced PET besides has the properties of PBT, still have the following characteristics: 1, thermal deformation temperature, and the long-term use of temperature is higher in thermoplastic general engineering plastics; 2, because of the high heat resistance, enhance the PET in 250 ℃ soldering tin bath soak 10 s, little deformation does not change color, especially suitable for the preparation of soldering of electronic, electrical parts; 3, the bending strength of 200 mpa, the elastic modulus of 4000 mpa, the creep and fatigue resistance is also very good, high surface hardness, mechanical properties similar to thermosetting plastic. 4, due to the production of PET glycol used than the production of PBT, the price of butyl glycol used, almost half cheap, so PET resin and enhance the PET is cheaper in engineering plastics, has the very high cost performance. Form of PET polyester is clear, light, squeezed or molded into plastic bottles and containers packaging of food and beverage, cosmetic containers, and many other consumer products. Such as glass, PET's health, strong, resistant to attack by microorganisms, don't react with food or drink, and will have no biodegradation. The use of its safety used in food and beverage is confirmed by the competent department of health all over the world. But I don't like glass, PET is very light and simple, transportation, and will not break, that is why it can be used in the cosmetics, food and beverage packaging. PET has been approved by the FDA for safety, health Canada, the European food safety authority and in the world, almost all of the other health and safety agency contact with food and drink. PET has been approved by the FDA for safety, health Canada, the European food safety authority and in the world, almost all of the other health and safety agency contact with food and drink. It has been used in food and beverage containers for decades without any known adverse effect. PET and PET packaging of a wide range of research indicate that it is safe again and again. 435.
