Many things used in people's lives are made of plastic materials, among which PP(Polypropylene/polypropylene) is widely used in plastic products.

PP is a thermoplastic polymer material, is a kind of polymer material, it is characterized by tough and durable, acid and alkali resistance, corrosion resistance, oxidation resistance and so on. Among them, PP has good processing performance, and can be made into products of various shapes and sizes by plastic molding, blow molding, etc., such as containers, bottle caps, household items, etc. Relatively speaking, the cost of PP plastic is relatively low, so it has a wide range of applications in the market.

So, what are the characteristics of PP in specific applications?

PP has a high softening point and can maintain stable physical properties in high temperature environments, so PP products are not easy to melt or deform. PP has high tensile strength and impact strength, so PP products are not easy to crack or break. At the same time, PP can well inhibit the generation of static electricity, so it is suitable for some industries that are sensitive to static electricity, such as electronics, medical and other industries.

In addition to the above characteristics, PP has some other advantages, such as high transparency, easy processing and forming, light weight and so on. These advantages make PP in the automotive, medical, home appliances, wire and cable and other fields have a wide range of applications. For example, oxidation pads made of PP materials, engine parts, rearview mirror housings, etc. are often used in automobiles; in the medical field, syringes, test tubes, and straws made of PP materials are very common products.

Although PP has many advantages, it also has some limitations. For example, PP has poor high temperature resistance and may be fluctuated under high temperature conditions, resulting in a decrease in physical properties. PP also has some problems in contact stability, especially when it comes into contact with some liquids with pigments or preservatives, PP may change color or become brittle.

In modern industry and life, PP, as one of the basic materials, has a wide range of important applications and plays a vital role. With the continuous development and progress of technology, I believe that PP will be more extensive and in-depth development and application in the future.
