PP-B is a raw material for chemical production, and its upstream and downstream related products are widely used in chemical industry, plastics, rubber, fiber and other fields. The following describes the upstream and downstream associated products of the PP-B in detail.

1. Upstream Associated Products

1. Propylene: The main raw material of PP-B is propylene, which is polymerized to produce polypropylene and further processed into PP-B. Therefore, the price and availability of propylene have an important impact on the production of PP-B.
2. Catalyst: The production of polypropylene requires the use of catalysts, commonly used catalysts are Ziegler-Natta catalysts and metallocene catalysts. The type and amount of catalyst have an important influence on the molecular weight, molecular weight distribution and performance of polypropylene.
3. Additives: In order to improve the processability and mechanical properties of the PP-B, it is necessary to add some additives, such as antioxidants, antistatic agents, lubricants, etc. The type and amount of these additives also need to be adjusted according to specific product requirements.

2. downstream related products

1. Plastic products: As a plastic raw material, PP-B is widely used in the production of various plastic products, such as pipes, plates, films, containers, etc. These products have excellent chemical corrosion resistance, electrical insulation and mechanical properties, and are widely used in chemical industry, building materials, food packaging and other fields.
2. Rubber products: PP-B can also be used to produce some rubber products, such as seals, hoses, etc. These products have excellent oil resistance, acid and alkali resistance, and are widely used in machinery, automobiles and other fields.
3. fiber products: PP-B can also be used to produce fiber products, such as polypropylene fiber. Polypropylene fiber has excellent wear resistance, corrosion resistance and other properties, widely used in clothing, home textiles and other fields.

In short, PP-B has a wide range of upstream and downstream related products, and its application fields cover chemical, plastic, rubber, fiber and other fields. With the continuous advancement of science and technology and the continuous improvement of application requirements, the upstream and downstream related products of the PP-B will continue to develop and innovate.
