Adjacent benzene is general-purpose colophony - 490, double-loop (DC) the hand papers colophony - 460, man-made stone / stone stone colophony - 500, pull crowded colophony - 520, twine structural layer colophony - 550, twine a benzene liner colophony - 540, colophony of NPG mould pressing - 500, colophony of DPG mould pressing - 830. Raw material market enters passageway of be issued to lower levels, colophony price reduces 300-500 considerably yuan. The condition that market of whole heavy goods has bilged in sluggish apparently issues the phase that entered “ sluggish ” , last as downstream market atrophic, industry of upriver raw material also must face reality to begin to undertake be adjustmented actively eventually, produce newly especially can the pressure that is about to put in the market, bring about chemical industry to taste the market to begin to appear situation of apparent weak force be issued to lower levels. Will tell with respect to UPR industry catenary, it is styrene market face on one hand Hua Yihe of benefit of Lin Mohua chemistry, Shandong presses down Hai Lian to change 2 period 3 large plants be about to the pressure of put into production and go up hard, additional on one hand the message that Hui Zhouyu arranges anhydride newly to begin trial production is forced eventually soare long already suitable anhydride market begins to turn around downward. Actually, whole UPR market is entered clear fatigued and weak position appeared after November, the actual output annulus of plant of quite most production drops apparently than appearing, had appeared to the demand of raw material clear weak sign, just the message of trial production of Yu Xinshun anhydride increased market pressure, quickened the fast be issued to lower levels of suitable anhydride price. To future of market of UPR of a phase go situation, we have as follows judged at 3 o'clock: One of, because at present whole UPR market is in weak force of be issued to lower levels, because this is before UPR price is stable, won't enter city stock up downstream, purchasing can be to deal with only produce place to need at the moment; Secondly, enter after December, the working key of UPR factory will change direction reclaim payment for goods is not production and sale, the difficulty of capital steam again this year can be unprecedented likely, what this need to cause whole industry chain is enough take seriously; Thirdly, later period still can have frigid weather, downstream to UPR production brings adverse effect. Accordingly we think, market of near future UPR won't appear to rebound apparently, will still retain weak power fatigued and weak condition. " 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.
