Plastic, as a material widely used in modern industry and life, has become an indispensable part of our lives. Although we often hear the concept of "plastic" in our daily life, few people really understand the material of plastic.

So, what are the different plastic materials? Below, we will introduce you one by one.

1. Polyethylene (PE)

Polyethylene is a thermoplastic. Because of its high transparency, good flexibility and excellent water resistance, it is widely used in packaging, toys, furniture and medical equipment. According to the density of polyethylene, it can be divided into three types: LDPE, MDPE and HDPE.

2. Polypropylene (PP)

Polypropylene is another common thermoplastic. It has the characteristics of hardness, wear resistance, high temperature resistance, and corrosion resistance, so it is widely used in auto parts, food packaging, Medical equipment and other fields.

3. Polycarbonate (PC)

Polycarbonate is a transparent, strong, weather-resistant and shock-resistant plastic material, which is widely used in electronic products, automobiles and construction industry.

4. Vinyl acetate copolymer (EVA)

Vinyl acetate copolymer is a kind of polymer material with excellent flexibility and wear resistance. It is widely used in shoe soles, sports mats, backpack heads and other fields, which can effectively protect human joints and other parts.

5. Polystyrene (PS)

Polystyrene is a thermoplastic with various colors, easy processing and low price. It is widely used in electrical appliances, furniture, daily necessities, toys and other fields.

In addition to these plastic materials, there are polyvinyl alcohol (PVA), polyester and polyether and many other materials. Each material has its own specific advantages and application scenarios. In industry and life, plastics are almost omnipotent, widely used and diverse in application fields.

by understanding the different plastic materials, we can better understand the application scope and characteristics of plastics, so as to better understand its importance in modern society. At the same time, when using plastics, we should also pay attention to dealing with damaged plastic products to minimize the impact on the environment.
