With the continuous advancement of industrialization and urbanization, plastic products have become an indispensable part of our daily lives. So, what is the difference between plastic and PP? Let's take a look at their raw materials, production processes and application areas.

1. raw material

plastic generally refers to the synthetic resin, according to its source is divided into petroleum-based plastics, bio-based plastics and other types. PP is the abbreviation of polypropylene, which is a thermoplastic obtained by the polymerization of propylene monomer. The difference between plastic and PP mainly lies in the different raw materials.

2. Production process
The production process of
plastics mainly includes raw material preparation, processing and molding, post-processing and other links. The production process of PP includes propylene monomer polymerization, post-processing and other links. Although the production process of both is more complex, but its purpose is to produce a special purpose plastic products.

3. Application field

plastics are widely used in automobiles, electrical appliances, furniture, building materials and other fields, such as plastic pipes, plastic furniture, plastic tableware, etc. PP is mainly used in the production of auto parts, electrical housings, packaging materials and other fields. In contrast, the application field of PP is relatively narrow, but its heat resistance, impact resistance, chemical resistance and other aspects show very excellent performance.

To sum up, although plastic and PP are common materials, the differences between them are still very obvious. Whether in raw materials, production processes, or applications, plastics and PP show their different characteristics and advantages and disadvantages. Therefore, in practical applications, we need to choose appropriate materials according to different needs and requirements to achieve the best use effect.
