Recycled PP (recycled polypropylene) plays an important role in the field of raw materials for chemical production. Its upstream and downstream related products are rich and diverse, involving plastics, rubber, fiber, coatings and other fields. The following are some of the main upstream and downstream related products:

1. upstream products:

(1) waste PP plastic: the main raw material of recycled PP is waste PP plastic, which comes from various plastic products in life, such as packaging bags, containers, household appliance shells, etc.

(2) Additives: In the production process of recycled PP, it is necessary to add some additives, such as antioxidants, anti-ultraviolet agents, toughening agents, etc., to improve the performance of recycled PP.

2. Downstream products:

(1) Plastic products: Recycled PP can be used to produce various plastic products, such as packaging bags, pipes, plates, containers, etc. These products have excellent acid and alkali resistance, corrosion resistance, high temperature resistance and other properties, widely used in chemical, food, medicine and other fields.

(2) fiber products: recycled PP can also be used to produce fiber products, such as polypropylene fiber. Polypropylene fiber has the advantages of light weight, high strength and good elasticity, and can be used to make clothing, plush toys, carpets, etc.

(3) Coatings: Recycled PP can be used as the basic raw material of coatings for the preparation of various functional coatings, such as waterproof coatings, anti-corrosion coatings, etc.

In short, the upstream and downstream related products of recycled PP are very rich, and their application fields are extensive, and they have high economic and social values. With the continuous progress of technology and the improvement of environmental awareness, the application prospect of recycled PP will be broader.
