SunSirs analysts believe that the decline in raw material prices has dragged down cis-butyl and styrene butadiene rubber; However, the start-up of BR and SBR units decreased, which supported their prices to a certain extent; In addition to the impact of natural rubber on synthetic rubber, it is expected that the price of BR may further decline in the later stage, and SBR will fluctuate in a narrow range.
