Demand for most commodity resins was generally lackluster in the first quarter and the beginning of the second. Both resin and monomer prices were generally soft. Nonetheless, polyethylene suppliers announced price increases in hopes of halting further erosion. Suppliers also are watching closely to see if processors start stocking up on resin as the hurricane season approaches.

PE prices down

Polyethylene prices dropped further in April, so the total slippage since December reached 18¢/lb. The drop last month was 2¢ as compared with 4¢ declines in each of the previous three months, perhaps signaling that prices are hitting bottom. Resin suppliers are attempting to show as much with a new price hike of 6¢/lb issued by most of the major players for May 1. Chevron Phillips and Formosa asked for only 3¢/lb.

There’s also upward price movement at the London Metal Exchange (LME), where May’s short-term futures contract in g-p butene-LLDPE for blown-film was 53.8¢/lb, up from April’s 51¢/lb.

Contributing factors: Some resin suppliers see low resin inventories at processors as a factor in their favor. They expect to implement their new prices, at least partially, either this month or in June.

Ethylene monomer contract prices dropped 3.5¢/lb in February and 2.5¢ in March. According to resin-purchasing consultant Resin Technology Inc. (RTI) in Fort Worth, Texas, monomer buyers are looking to shave off another 1¢ to 3¢ to close the unusually big gap between contract and spot prices. March contract prices stood at 47.5¢/lb and spot prices were in the low 30¢/lb range.

PP prices flat

Polypropylene prices were stable in early April, after moving up 4¢ to 6¢/lb in the previous two months. There was industry chatter that a new price increase would be announced for May or June. However, the LME’s May short-term futures contract for g-p injection-grade PP homopolymer is 50.1¢/lb, down from April’s 51¢/lb.

Contributing factors: Attractive resin deals were available into early April, and RTI sources said some processors were already “getting back” 4¢/lb of those earlier price hikes. Still, suppliers expect some uptick in demand in the second quarter, and perhaps a bit more. Says one major supplier, “There is lots of talk about hurricane stockpiling.”

Propylene monomer prices moved up a total of 6¢/lb from January to March, and April contracts seemed likely to rise another penny or two.

PVC falls 2¢

As expected, PVC resin prices lost 2¢/lb in March, while resin producers delayed their pending 2¢ increase yet again, this time to May 1. It was originally announced for January 1.

Contributing factors: PVC demand was still weak in mid-April, with no sign of the usual spring build-up. Falling ethylene monomer prices are also putting downward pressure on PVC.

PS continues to weaken

Polystyrene prices, already down about 6¢ from November through March, were expected to lose another 1¢ to 2¢/lb in April. Styrene monomer was flat in mid-April, but spot monomer fell as low as 45¢/lb, which was below cost.

Contributing factors: Polystyrene is still in oversupply, and demand is weak for this time of year, which is usually fairly strong. March demand was perhaps 10% below normal for what is usually a strong month. High resin prices have hurt PS in cup, lid and cutlery markets, which have shifted to paper, PET, and PP respectively. In durable goods, however, PS is still strong for the time of year, resin producers say.

Composite resins rise

Owing to continuing petrochemical supply disruptions caused by Hurricane Katrina, isopthalic acid feedstock for unsaturated polyesters has been more expensive and hard to get. That’s the reason cited by AOC, which hiked all its isophthalic-based resins and gel coats by 3¢/lb on May 1.
