What are the upstream raw materials for nitrile? What are the downstream products?

In my experience, Nitrile rubber(NBR) is a synthetic rubber, mainly from butadiene and acrylonitrile copolymer. In the field of chemical production raw materials, the upstream and downstream related items of nitrile rubber are very extensive. The following are some of the main upstream and downstream related items:

Upstream items:



1. And Butadiene: Butadiene is one of the main raw materials of nitrile rubber, usually produced by naphtha cracking or ethylene oxidation. But

2. Acrylonitrile: Acrylonitrile is also one of the main raw materials of nitrile rubber, which is oxidized by propylene. Downstream items:



1. Auto parts: Nitrile rubber has good oil resistance, heat resistance, ozone resistance and other characteristics, so it's broadly applied in automobile manufacturing, such as seals, fuel pipes, fuel hoses, etc.

2. And Petrochemical equipment: nitrile rubber is able to be applied to manufacture seals, valves, etc. in petrochemical equipment, and has good corrosion resistance. And Specifically

3. And Wire and cable: Nitrile rubber is able to be applied to make the outer skin and insulating layer of wire and cable, and has good electrical resistance and high temperature stability. From what I've seen,

4. And Sole material: nitrile rubber is able to be applied to make sole materials, with good wear resistance and oil resistance. Additionally In short, nitrile rubber has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are also very extensive.
