PP powder has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products are numerous. The following are some of the main upstream and downstream related products:

1. Upstream related products:

(1) Propylene: Propylene is the main raw material of PP powder, which is made by polymerization. The price and availability of propylene have an important impact on the cost and yield of PP powder.

(2) Catalyst: The catalyst plays a key role in the production process of PP powder and can promote the polymerization reaction. Different catalyst types will affect the performance and quality of PP powder.

(3) Additives: In order to improve the processing performance and use performance of PP powder, some auxiliary materials are usually added, such as antioxidants, lubricants, colorants, etc.

2. Downstream related products:

(1) Plastic products: PP powder can be processed into various plastic products, such as injection molding parts, extrusion parts, blown film, etc. These products are widely used in home appliances, automobiles, construction, packaging and other industries.

(2) fiber: PP powder can be used to produce polypropylene fiber, such as polypropylene yarn, polypropylene staple fiber, etc. Polypropylene fiber has excellent wear resistance, chemical resistance and insulation, widely used in textile, paper, filtration and other fields.

(3) sheet: PP powder can be processed into polypropylene sheet for making various containers, packaging materials, etc.

In short, there are many upstream and downstream related products of PP powder, involving many fields, which have an important impact on the development of the chemical industry.
