Adjacent benzene is general-purpose colophony - 590, double-loop (DC) the hand papers colophony - 800, man-made stone / stone stone colophony - 370, pull crowded colophony - 430, twine structural layer colophony - 530, twine a benzene liner colophony - 530, colophony of NPG mould pressing - 600, colophony of DPG mould pressing - 760. Raw material market considerably be issued to lower levels, colophony price reduces 300-600 yuan. Raw material market is overall last week be issued to lower levels, arrange type of anhydride price occurrence bluff to drop especially, mellow the price of kind of product also goes weak in the round, after styrene falls first, rise. At present raw material market faces ternary pressure: It is New Year falls firstly to, downstream market demand is fatigued and weak; It is new increase production secondly can start working message is ceaseless, supply increases; It is downstream client thirdly desire of the stock up year ago is not strong. This week was 2021 hind a week, 2022 next the Spring Festival comes before, the production that also has much Zhou Duo only is periodic, and from downstream feedback the information that come back looks, of Hu Nianchun section have a holiday time should shift to an earlier date generally than in former years, accordingly, the manufacturing time of UPR industry has been entered before spending the New Year time, company of the UPR year ago is right the significant demand of raw material already very finite. After the Spring Festival passes, raw material market is about to face the difficult problem that supply ability raises considerably. In light of styrene, china beneficial mixes Shandong benefit 720 thousand tons the refine that press down the sea is changed 2 period buy of 650 thousand tons of these two new clothes will be in put into production of near future start working, add early days to jockey the device of the overhaul will be after the Spring Festival in succession put into production, because this increased the styrene after the Spring Festival to supply greatly; As to suitable anhydride, at present Hui Zhouyu is being produced newly can climb slope level, the daily output after predicting Spring Festival will increase 3 times current, and Jiang Ningshun anhydride also will drive in Spring Festival around, lacks because of exit yield can breach got be redeeminged effectively not only, and somewhat rich; 2 pleasant alcohol and third also have new increase production after 2 mellow Spring Festivals can anticipate, accordingly, from the point of market of whole UPR raw material, spring Festival hind appears generally produce the current that can increase considerably, the UPR factory of the stock up before this will give intentional Spring Festival and downstream client create enormous psychological pressure. As to UPR market level, we predict, the near future will still continue condition of current weak force be issued to lower levels. " 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.
