What are the upstream raw materials for polypropylene? What do the downstream products contain?

Polypropylene(Polypropylene, referred to as PP) is a common polymer compound, broadly applied in the field of chemical production raw materials. There are many upstream and downstream related items of polypropylene, and some of the main upstream and downstream items will be described in detail below. Upstream items:



1. Propylene: The main raw material of polypropylene is propylene, and propylene is polymerized to create polypropylene. I've found that Propylene production methods mainly include naphtha cracking, propane dehydrogenation, ethylene by-product and so on.

2. Catalyst: The production of polypropylene needs the consumption of catalysts, frequently applied catalysts are Ziegler-Natta catalysts, metallocene catalysts, etc. In particular Downstream items:



1. Based on my observations, Plastic items: Polypropylene has excellent chemical resistance, heat resistance, electrical insulation and processing characteristics, so it's broadly applied in the production of various plastic items, such as pipes, containers, films, fibers, etc.

2. But I've found that Fiber: Polypropylene fiber is a common chemical fiber, with high strength, good elasticity, wear resistance and other characteristics, broadly applied in textiles, non-woven fabrics and other fields. For example

3. And Building materials: Polypropylene is able to be applied to create building materials, such as pipes, plates, profiles, etc. It has the advantages of light weight, corrosion resistance, and easy processing.

4. Based on my observations, Auto parts: Polypropylene is able to be applied to create auto parts, such as bumpers, dashboards, seats, etc. Makes sense, right?. I've found that It has the characteristics of light weight, high strength and low cost.

5. Home appliances: Polypropylene is broadly applied in the production of home appliances, such as washing machines, refrigerators, atmosphere conditioners, etc. And According to research, to the manufacture of shells, parts, etc. In short, there are many upstream and downstream related items of polypropylene, involving various fields, which is of great signifiis able toce to the research of chemical production raw materials.
