Adjacent benzene is general-purpose colophony - 40, double-loop (DC) the hand papers colophony - 60, man-made stone / stone stone colophony - 100, pull crowded colophony - 80, twine structural layer colophony - 50, twine a benzene liner colophony - 100, colophony of NPG mould pressing - 70, colophony of DPG mould pressing - 100. Hasten of concussion of raw material market is firm, colophony price keeps stable. Before raw material market was experienced last week tall hind low considerably concussion process, but from average cost fluctuant extent looks, not big to the influence of UPR cost, and most UPR factory is purchased futures of costly suitable anhydride is in even this week delivers the goods next week even, because company of this UPR production is nonexistent,reduce the space of price. From 2 weeks of prices before fluctuant case looks, the UPR plant that fluctuate as raw material price at that time and reduces price considerably compares passivity in the process that here second price rises considerably, normally accordingly the circumstance falls, when we suggest UPR factory is adjusting price, should produce mutation likely to raw material market this kind of circumstance takes superabundant land. Hui Zhouyu arranges anhydride product newly to appear on the market last week the sale created constant pressure to Hua Na market, but at present Yu Xin is produced can climbing slope level, temporarily short-term inside the impact that won't cause materiality to the market. Look at present from the start working circumstance of each UPR factory, the order in the hand still can keep this week second half paragraph time, again the rate of real go into operation of predicting UPR of in the future will fall apparently. Accordingly, we predict, suitable anhydride price appears directional transform and not be short-term concussion prices, should when this week second half paragraph mix next week first, at the appointed time manufacturing bear of Yu Xin also will elevate normal level, in the meantime, next week end again next week first, zhejiang river arranges anhydride to enter the pre-construction phase that resumes production likely rather, also can bring constant pressure to the market at the appointed time. As to styrene prices, press down solution of sea area epidemic situation to seal as Ning Bo, the factory resumes production in succession, the styrene product that the refine that press down the sea turns will return market, and emperor also is doing northward jade to drive afresh answer the preparation that produce, below this kind of circumstance, styrene market will face greater pressure. Look on the whole, short-term inside UPR price will keep stable, future whether go weak, should see this week second half the metabolic circumstance of market of Duan Yuan data. " 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.
