Adjacent benzene is general-purpose colophony 260, double-loop (DC) the hand papers colophony 280, man-made stone / stone stone colophony 290, pull crowded colophony 310, twine structural layer colophony 290, twine a benzene liner colophony 210, colophony of NPG mould pressing 290, colophony of DPG mould pressing 350. Raw material market rebounds in the round, the spurt in prices that arrange anhydride, supply of goods is strange be short of, 300 yuan are moved on colophony price. Market of this week raw material is overall weak force rebounds, but in exit increment and part produce business equipment below the influence that breakdown weak point stops, suitable anhydride price again hurricane is pulled go up, and supply of goods surprises be short of, bring about UPR product cost to increase, the factory produces bear to drop in the round. Especially northward market, the impact that is supplied by suitable anhydride is bigger. At present UPR market needs the key of attention: The supply that is suitable anhydride first circumstance, look at present short-term inside still alleviate hard, and the severe shortage of suitable anhydride is great the output that restricted UPR, can give partial area to cause UPR to supply the situation with progressively tight hasten thereby, this kind of circumstance is in prospective 1-2 Zhou Youke can be more outstanding, especially the prices of downstream stock up before later period the Mid-autumn Festival and National Day grow a holiday, the unbalance that UPR of possible meeting aggravate supplies. It is the demand situation with at present downstream UPR next, short-term look relatively fatigued and weak still. The 3rd it is to will begin on September 1, northward 2+26 city starts air of Beijing Olympic Winter Games to pollute a canal to accuse measure, can produce to enterprise of this region chemical industry bring an influence, do not eliminate partial period of time to appear to reduce negative likelihood in the round. Altogether, in at present of level UPR market be forced to go up tone price, will tell to whole industry catenary is a good news by no means, meeting more the manufacturing enthusiasm that hits downstream industry, especially price of fine of near future Bo also appeared to rebound, this is one disaster after another more to downstream FRP industry, the sluggish of UPR industry bilges feature will more apparent. In the market the environment of queasy adventitious falls, we recommend below " experience introduction " medium practice: " 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.
