In September, the cost support for NBR was weak, and the increase in NBR production increased the pressure on the market supply side; In addition, during the traditional peak season downstream, the production of rubber hoses and insulation foam industries has significantly increased, which supports the NBR market.

As of September 28th, the mainstream market price for Lanhua 3305 in East China is around 16,300-16,400 RMB/ton; The mainstream market price for Nandi Nitrile 1052 is around 17,500-17,600 RMB/ton; The mainstream market price for nitrile 2665 in Russia is around 15,900-16,000 RMB/ton.
In September, the domestic NBR plant started construction and increased, and the Shunze nitrile plant has recently restarted; As of September 28th, the overall production of NBR in China is around 80%.
In September, the price of raw material butadiene slightly decreased and the price of acrylonitrile slightly increased, resulting in weak cost support for NBR.
