Adjacent benzene is general-purpose colophony 240, double-loop (DC) the hand papers colophony 180, man-made stone / stone stone colophony 270, pull crowded colophony 260, twine structural layer colophony 260, twine a benzene liner colophony 230, colophony of NPG mould pressing 100, colophony of DPG mould pressing 290. Raw material market rebounds continuously, colophony cost continues to rise, market price go up again move 300 yuan. This Zhou Yuan cost of material continues concussion goes up, arrange anhydride and 2 pleasant alcohol especially relatively driving, at the same time styrene and benzene anhydride also concussion goes tall, third 2 alcohol are to be achieved again more piece old new tall. Here prices falls, UPR is forced to follow on tone price. UPR downstream demand is at present good, UPR plant go into operation is led relatively early days rises apparently. Before no less than we analyse all the time since a few weeks in that way, after tomb-sweeping day passes, the market is in downstream demand to restore stage by stage, and company of production of upriver raw material begins by turns stop production overhauls faults of such a kind of “ to match ” prices, bring about base point of market price check thereby progressively drive up, and breed of partial raw material for example epoxy resin price has achieved the history repeatedly new tall, bring about vinyl ester colophony thereby continuous go up continuously tone price. From at present raw material market goes in light of situation, partial breed still is in ascendant passageway in, especially with the suitable anhydride closely related UPR, increase as what upriver stop production overhauls dimensions, still have the possibility that rises continuously. And at present commercial inventory is in 2 pleasant alcohol extremely low, partial market personage worries about the likelihood of ” of existence “ run out of grain even. As to styrene, although the market go up to issue concussion to move suddenly suddenly, but stock is at present small, outside dish arrive decrease, domestic unit is overhauled thick and fast, extra capital acclaims this three-layer element, also put in short-term value to jump the likelihood that go up. Anyhow, still be us early days analyses for many times in that way, downstream market demand anabiosises is this one main impetus that rise in price, time can last to the last ten-day of a month in May likely.
