1. What is plastic PP?

plastic PP, also known as polypropylene, is a thermoplastic plastic with simple structure, low melting point, good molding performance, high mechanical strength and so on. PP is widely used in engineering fields because of its good corrosion resistance, permeability resistance and thermal stability.

2. The characteristics of PP

① Corrosion resistance: PP has very good chemical stability and is not easily corroded by acids, alkalis and other chemicals.

② processability: PP can be processed into various shapes by blow molding, extrusion, injection molding and other methods.

③ high mechanical strength: PP has high tensile, bending and impact strength, and is not easy to deform.

④ Anti-permeability: PP has good waterproof performance and can be used to make various waterproof products.

⑤ High temperature resistance: PP's use temperature range is within 85 ℃, so it also has good performance in high temperature environment.

3.PP application

PP wide application is mainly reflected in the following aspects:

① daily necessities: PP can be used to make a variety of daily necessities, such as baby bottles, cups, tableware, etc.

② packaging materials: PP can make all kinds of packaging materials, such as food packaging bags, plastic wrap, etc.

③ Engineering field: PP is widely used in the engineering field, such as auto parts, pipes, electrical housings, etc.

④ Medical field: PP has good medical performance and can be used to make various medical devices and appliances.

4. The advantages and disadvantages of PP

advantages: PP has good physical and chemical properties, is easy to process and shape, and has good cost-effectiveness.

disadvantages: PP has low hardness and is susceptible to impact cracking; PP has relatively poor heat resistance and cannot be used in high temperature environments.

Although PP has some shortcomings, its advantages far outweigh its disadvantages, so it has been widely used. It is hoped that through the introduction of this article, readers can have a more comprehensive understanding of PP.
