Goodyear declares force majeure on SBR

Towards the end of May, US manufacturer Goodyear released a statement reporting it had declared force majeure on styrene butadiene rubber (SBR) and other butadiene (BD) derivatives because its supplier is short of these substances. “While we are working diligently to identify and obtain alternative sources of butadiene monomer supply, at this time we do not know how long the situation will last,” the statement read.
