Upstream and downstream related products
of polymer-grade propylene
polymer-grade propylene is an important chemical raw material, widely used in the production of plastics, synthetic rubber, synthetic fibers and other polymer materials. As the core raw material for chemical production, the upstream and downstream related products of polymer grade propylene are very rich. This article will detail the upstream and downstream associated products of polymerization grade propylene.

1. Upstream Products

1. Petroleum

The main source of polymer-grade propylene is petroleum cracking. In the process of petroleum processing, low-carbon olefins including propylene can be obtained by cracking hydrocarbon feedstocks such as naphtha and light diesel oil.

2. Natural gas

The main component of natural gas is methane, which can be converted into propylene by steam cracking or oxidative dehydrogenation.

2. Downstream Products

1. Polypropylene

Polypropylene is the most important downstream product of polymerization grade propylene. It is a thermoplastic with excellent chemical resistance, electrical insulation and processing performance. It is widely used in packaging, Automobiles, home appliances, building materials and other fields.

2. Styrene-butadiene rubber

Styrene-butadiene rubber is a kind of synthetic rubber, which is copolymerized by polymerization grade propylene and styrene. It has excellent wear resistance, aging resistance and processing performance, widely used in tires, shoes, pipes and other fields.

3. Acrylonitrile

Acrylonitrile is an important organic chemical raw material, which is prepared by the reaction of polymer-grade propylene with ammonia and oxygen under the action of catalyst. Acrylonitrile can be used in the production of acrylic fiber, nitrile rubber, acrylic and other chemicals.

4. Propylene oxide

Propylene oxide is a cyclic ether compound, which is produced by the oxidation of polymerization grade propylene and hydrogen peroxide. It is an important organic chemical raw material, which can be used to produce propylene glycol, polyurethane, acrylic and other chemicals.

In short, polymer grade propylene has a pivotal position in the field of chemical production raw materials, and its upstream and downstream related products are extensive, involving plastics, rubber, fiber and other fields. With the continuous development of science and technology, the upstream and downstream products of polymer-grade propylene will continue to expand and enrich, injecting new vitality into the development of the chemical industry.
