HOUSTON (ICIS)--US styrene-butadiene-rubber (SBR) contract prices for July fell by several cents/lb, in line with the drop in feedstock butadiene (BD) costs, market sources confirmed on Wednesday.
ICIS-assessed contract prices for non-oil grade 1502 SBR were 97-109 cents/lb ($2,138-2,403/tonne) in July compared to 102-112 cents/lb in June.
July contract prices for oil-extended grade 1712 SBR were 93-105 cents/lb, down from 97-107 cents/lb in June.
Some July SBR contracts are based on June BD contract prices, which fell by 3 cents/lb for three separate producers and 2 cents/lb for one producer.
Other July SBR contracts are based on July BD contract prices, which settled at drops of 3 cents/lb for three producers and 5 cents/lb for one producer.
For other SBR feedstock styrene, May contract prices had fallen by 1.5 cents/lb, although the settlement had less of an impact on SBR contract prices.
North American SBR producers include American Synthetic Rubber Co, Ashland, East West Copolymer & Rubber (Lion Copolymer), Firestone Polymers, Goodyear Tire & Rubber, LANXESS and Negromex.
