Coating Antifog APET Plastic sheet for face shield

APET has a highly symmetrical molecular structure and a certain crystal orientation ability, so it has high film-forming properties and properties. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent wear resistance, friction, dimensional stability and electrical insulation. PET bottles have high strength, good transparency, non-toxic, anti-permeation, light weight, high production efficiency, etc., so they are widely used. The molecular chain structure of PBT and PET is similar, and most of the properties are the same, except that the main molecular chain has changed from two methylene groups to four, so the molecules are more flexible and processing performance is better.

Advantages of APET as a packaging material:
1. It has good mechanical properties, impact strength is 3 to 5 times that of other films, and good folding resistance.
2. Resistance to oil, fat, dilute acid, dilute alkali, and most solvents.
3. With excellent resistance to high and low temperatures, it can be used for a long time within the temperature range of 120°C, and can withstand high temperatures of 150°C and low temperatures of -70°C in short-term use, and has little effect on its mechanical properties at high and low temperatures.
4. The gas and water vapor permeability is low, and it has excellent gas, water, oil and odor resistance.
5. High transparency, can block ultraviolet rays, and good gloss.
6. Non-toxic, tasteless, good hygiene and safety, and can be directly used for food packaging.
