PET, polyethylene terephthalate –plastic injection molding material
PET material parts
The most common use as beverage bottles and other transparent screen protection film protective film. PET can also be spinning, that is, we often say polyester. In addition, there are many engineering applications PET
1. PET plastic transparent bottle is resistant to oil, fat, dilute acid, dilute alkali, and most solvents.
2, The plastic transparent bottle has good mechanical properties, the impact strength is 3 to 5 times of other films, good folding resistance.
3. PET plastic transparent bottle has excellent resistance to high and low temperatures. It can be used in the range of 120℃ for a long time, 150℃ for a short time, and -70℃ for a short time.
4, PET plastic transparent bottle gas and water vapor permeability is low and has excellent gas, water, oil, and odor performance.
5. The use temperature of the PET plastic transparent bottle should not exceed 70℃. It is non-toxic, tasteless, hygienic, and safe, and can be directly used for food packaging.
6, high transparency, can block UV, good gloss.
Non-toxic, but the synthesis process may remain single, low molecular weight oligomers and side reaction products such as diethylene glycol, these are some toxic, PET raw material for beverage bottles countries have strict standards.
PET plastic injection molding a higher melting point. But generally do not recommend reusing bottles, especially for loading water. Since PET bottles are generally thin, manufactured using a blow molding method, when the bottle is heated to about 90 ℃ rearrange, and the internal stress due to the role of PET molecular chains, and the contraction distortion of the bottle experience, this time using easily result in burns. The higher temperatures will increase the risk of harmful substances in the material eluted.
