In August 2025, prices for Hydrogenated Nitrile Butadiene Rubber (HNBR) in the US fell due to plenty of inventory available, and a 3.69% decrease in butadiene feedstock prices. Although demand from the automotive and aerospace markets was steady, low downstream offtake and erratic procurement strategies affected market sentiment. Manufacturers would be able to maintain margins through efficiencies on spending, while buyers were sourcing on a hand-to-mouth basis due to macroeconomic uncertainty.
