Adjacent benzene is general-purpose colophony - 70, double-loop (DC) the hand papers colophony - 20, man-made stone / stone stone colophony - 150, pull crowded colophony - 120, twine structural layer colophony - 110, twine a benzene liner colophony - 90, colophony of NPG mould pressing - 220, colophony of DPG mould pressing - 140. Hasten of wave motion of raw material market is firm, colophony price keeps stable. Raw material market rises last week drop each other shows, the price of partial breed is in new increase production can appear to rebound apparently below the effect that start working delays. What this week needs to pay close attention to is the new progress that Hui Zhouyu arranges anhydride trial production newly, and rehabilitate of check of northward styrene factory produces a situation, if this two respects still do not have new progress, do not eliminate to arrange the possibility that anhydride and styrene price rebound further. At present UPR industry catenary enters low-level steady state, whole industry catenary holds inferior stock, just wanted market stability. Enter a month after this year, sales volume is not the main factor that UPR factory considers any more, the working focal point that the factory carries has begun to change capital steam again to the respect, because this price stability is current the main feature of UPR market, the condition photograph link up with of the product price of partial plant and steam again capital. Before been adjust as a result of the raw material price of major UPR low a level, only 2 alcohol still are in suitable anhydride and third relatively higher-priced, look from whole accordingly, of UPR price reduce a space already apparent and finite. " experience introduction " : The downstream client of UPR is more very with export or project kind the market is relevant, accordingly downstream user often hopes to be in accept the order when can will export order for goods or one-time all lock decides the UPR amount that project order place needs and value, but the force with upriver market because UPR industry is right enough lack and control force, the price of UPR factory can passive follow of price of upriver raw material change and undertake adjustment. Accordingly, every time UPR price appears relatively during changing substantially, create the contradiction between UPR factory and downstream user easily. Divide the experience of the enterprise according to eye forehead, good means of settlement is UPR produces factory and downstream client to undertake deepness bind, the interest shares everybody, the risk is carried together, who doesn't blame. Particular way is: In sign gross contract when, sign a price to change adjust methodological clause, namely basis " colophony price index " the price index that publishs is fluctuant extent, both sides assumes price index severally 50% of fluctuant part, calculate every week the price, implement the price actually as what delivering goods day is in a week. The practice of partial enterprise proves, this kind of method not only fairness is reasonable, and those who have the price but foresight, need not both sides delivers goods every time want bargain. This experience consults for everybody.
