PPR(Polypropylene Random Copolymer, random copolymer polypropylene) is a widely used raw material in the field of chemical production. In the upstream and downstream related products of PPR, the upstream products mainly include propylene, catalysts and other raw materials, while the downstream products cover pipes, pipe fittings, plates, fibers, injection molding products and other fields.

1. upstream related products

1. Propylene

Propylene is the main raw material for the production of PPR, accounting for a large proportion of PPR production costs. The market price fluctuation of propylene has an important influence on the production cost of PPR.

2. Catalyst
The production of
PPR requires the use of a catalyst to promote the polymerization of propylene. Commonly used catalysts include Ziegler-Natta catalysts and metallocene catalysts.

2. downstream related products

1. pipe

PPR pipe is the main application field of PPR, with excellent corrosion resistance, heat resistance, pressure resistance and environmental protection, widely used in construction, municipal, water conservancy and other fields.

2. Pipe Fittings

PPR pipe fittings are important accessories for connecting PPR pipes, including elbows, tees, crosses, valves, etc., used to change the direction of water flow and adjust water flow.

3. plate

PPR plate has the characteristics of light weight, high strength, waterproof and moisture-proof, easy processing, etc., and can be used in furniture, construction, packaging and other fields.

4. Fiber

PPR fiber has excellent corrosion resistance, heat resistance, abrasion resistance and elasticity, and can be used to make industrial textiles, filter materials, etc.

5. Injection molding products

PPR can also be used to produce various injection molding products, such as containers, bottle caps, toys, etc.

In summary, the upstream and downstream related products of PPR cover many fields of chemical production and have a wide range of applications. With the continuous progress of science and technology and the expansion of application fields, the production technology and application scope of PPR and its related products will continue to be developed and improved.
