HOUSTON (ICIS)--US styrene-butadiene-rubber (SBR) contract prices for June were assessed on Thursday at a rollover or slight decrease, depending on the supplier, in line with the contract price movement for main feedstock butadiene (BD).
ICIS-assessed June contract prices for non-oil grade 1502 SBR were 102-112 cents/lb ($2,249-2,469/tonne) FOB (free on board), compared to 104-114 cents/lb the previous month.
June oil-extended grade 1712 SBR contract prices were assessed at 97-107 cents/lb FOB, compared to 98-108 cents/lb in May.
Despite varying levels of reductions in individual contracts, several market participants confirmed that their June contract pricing fell within or close to the published range above.
Some June SBR contracts were based on May BD contract prices, which settled at rollovers, so June SBR contracts had little or no change from the previous month, a producer said.
However, other June SBR contracts were based on June BD contract prices, which settled down 3 cents/lb for three producers and down 2 cents/lb for one producer.
For 1502 SBR contracts, another producer said its June prices decreased by about 2.5 cents/lb, while traders and buyers said they saw prices drop by 1-3 cents/lb.
The producer said its June 1712 SBR contract prices fell by about 1.8 cents/lb, while those on the buy side said they ticked down by about 1 cent/lb.
For other feedstock styrene, April contracts had fallen by 2 cents/lb, but the monomer had less of an impact on SBR contract pricing.
North American SBR producers include American Synthetic Rubber Co, Ashland, East West Copolymer & Rubber (Lion Copolymer), Firestone Polymers, Goodyear Tire & Rubber, LANXESS and Negromex.
