Adjacent benzene is general-purpose colophony - 170, double-loop (DC) the hand papers colophony - 130, man-made stone / stone stone colophony - 310, pull crowded colophony - 320, twine structural layer colophony - 300, twine a benzene liner colophony - 330, colophony of NPG mould pressing - 140, colophony of DPG mould pressing - 560. Hasten of concussion of raw material market is weak, colophony price reduces 200-300 yuan. Market of whole chemical industry has bilged from the “ of early days ” changed current “ sluggish to ” , entered sluggish to bilge the second half of level period. Of early days bilge, when lasting more than one year about, and the sluggish of later period, our estimation also will comparative continuously long period of time. At present influence market goes the element of situation to have 4 as follows: One of, from prevent consideration of occurrence hyper inflation, macroscopical policy level objects the abidance of the price rising, this take up a political career government office is puissant dozen press coal price to see one spot, because this is mixed with center look forward to,the company of production of big chemical industry that the civilian look forward to of kind of center look forward to is is continueing to rise in price “ has changed direction to tell political ” from pursuit economic benefits stage by stage on this problem, conscious control price rises further; Secondly, in nearly one year of many price after rising continuously, of whole industry catenary had can'ted bear heavy burden downstream, market demand occurrence atrophy, perch of supply demand relations is turned round, what market element also does not support the price is farther rise substantially; Thirdly, rove of international oil price, the market continues to rise in price considerably hope is scant; Its 4, winter is freezing as scheduled be caused by, downstream production rhythm is apparent rein in, outdoors construction stops basically, off-season feature strengthens the market apparently. Because this looks from above element, market of near future chemical industry will appear exalted look forward to firm, and firm in the feature with weak hasten. But still be in inflationary phase as a result of whole market, international oil price still possible phase sex goes tall, upriver enlarge produces plan to be able to be later than likely anticipate, because of the situation that this UPR market won't appear to drop quickly, will enter slowgoing shade to drop level. " 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.
