Read： 384 Time：22months ago Source：Transform the World with Simplicity

As a new material in modern materials science, plastic PET has been widely used in various industries. So, what is plastic PET? What are the advantages and disadvantages? What is it suitable for?

we need to understand what is PET. PET, namely polyester, is a plastic material with excellent physical and chemical properties, including heat resistance, chemical corrosion resistance, transparency and so on. The plastic PET is a natural polymer material composed of polyacrylate, which has high strength and hardness, and at the same time has good flexibility and wear resistance.

So, what are the advantages of plastic PET?

1. Good transparency and gloss, making it an excellent packaging material, especially for high-demand industries such as food and medical devices.

2. Good mechanical properties make it have high strength and hardness, suitable for manufacturing various industrial supplies.

3. Good chemical resistance, heat resistance and weather resistance, suitable for various chemical fields.

In addition to these advantages, plastic PET has some shortcomings that need to be paid attention to, such as it is not resistant to high temperatures and cannot be used for high temperature processing, and its environmental protection is also controversial. Therefore, it is necessary to pay attention to its limitations during use.

So, plastic PET is suitable for what areas?

1 packaging industry

plastic PET can make transparent packaging materials, and its appearance is bright, making it a very suitable for food, medical equipment and other high demand industry packaging materials.

2. Industrial

plastic PET has high mechanical properties and can produce various industrial supplies that require strength and hardness, such as auto parts, machine parts, etc.

3. chemical industry

plastic PET chemical resistance makes it can be used to make a variety of chemical products and liquid containers.

In summary, plastic PET is a new type of material with wide application prospects. It has good transparency, mechanical properties and chemical resistance. Of course, it also has some limitations. In the process of use, we need to pay attention to its characteristics and application areas, in order to play the greatest practical value.
