Adjacent benzene is general-purpose colophony - 190, double-loop (DC) the hand papers colophony - 210, man-made stone / stone stone colophony - 130, pull crowded colophony - 110, twine structural layer colophony - 140, twine a benzene liner colophony - 110, colophony of NPG mould pressing - 120, colophony of DPG mould pressing - 80. Weak potential of raw material market is adjusted, double-loop kind colophony price reduces 200 yuan, the others breed keeps stable. Weak force adjusts market of this week raw material. UPR downstream market still is in weak moving condition, guangdong area suffers effect of new coronal epidemic situation, whole industry catenary produces rhythm to be thrown into confusion thoroughly. Northern region enters season of wheat harvest busy season, be brought the influence of full inspection at the same time, downstream trade go into operation is led relatively early days appears to drop apparently. Whole UPR industry still sink is low a phase that run. We predict, at present this kind of flat condition should last to the end of the month at least. Deserving attention is, current economic operation pattern appeared it seems that directional adjustment, severe to estate the cry recrudesce that accuse, the rumor that all sorts of adjusting control measure are about to publish is incessant Yu Er, at the same time the foundation builds dimensions to also have the tendency that reduce, the tendercy of this two respects is told to UPR industry catenary put in the effect with relatively negative move, need causes the high vigilance of industry. " 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.
