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 products of nitrile rubber are very extensive. The following are some of the main upstream and downstream related products:

Upstream products:

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

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

downstream products:

1. Auto parts: nitrile rubber has good oil resistance, heat resistance, ozone resistance and other properties, so it is widely used in automobile manufacturing, such as seals, fuel pipes, fuel hoses, etc.

2. Petrochemical equipment: nitrile rubber can be used to manufacture seals, valves, etc. in petrochemical equipment, and has good corrosion resistance.

3. Wire and cable: Nitrile rubber can be used to manufacture the outer sheath and insulating layer of wire and cable, and has good electrical resistance and high temperature stability.

4. Sole material: Nitrile rubber can be used to make sole materials, with good wear resistance and oil resistance.

In short, nitrile rubber has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related products are also very extensive.
