Adjacent benzene is general-purpose colophony - 130, double-loop (DC) the hand papers colophony - 220, man-made stone / stone stone colophony - 100, pull crowded colophony - 110, twine structural layer colophony - 160, twine a benzene liner colophony - 160, colophony of NPG mould pressing 190, colophony of DPG mould pressing - 370. Concussion of raw material market splits up, colophony price keeps stable, the market enters the Spring Festival to have a holiday to time. Raw material market rises last week drop each other shows, partial product issues tourist door to begin to get the materials ready, partial product suffers the Yangtse River to ban boat influence to rise in price, partial product gets slow down in demand and new increase production can put into production anticipates the influence drops continuously. Look on the whole, UPR market begins to enter the Spring Festival to have a holiday to time from this week mode, below this week half time begins, partial line-haul danger is changed taste content shedding to begin to halt use in succession, downstream client worker begins to have a holiday in succession come home spend the New Year, market demand begins to enter materiality to reduce volume level. This period, the publicity of the price is adjusted had done not have any meanings, no matter be raw material or UPR product, basically be the basis purchases amount and payment to adopt one onefold the method that talk, stock up of Spring Festival of base oneself upon and reduce inventory pressure to discuss trading terms. Notable is, the mood of Spring Festival stock up of catenary of industry of whole this year UPR is not tall, at the same time Jiangning arranges anhydride to produce device to had restarted, market of this suitable to Spring Festival around anhydride can bring more pressure; In the meantime, shandong benefit 720 thousand tons of styrene and town sea refine turn China profit 2 period 650 thousand tons of styrene also is in at any time can the condition that put into production starts, accordingly, the raw material market after the Spring Festival still is faced with new increase production can main effect. Before the Spring Festival, UPR market is overall and stable, the price is certain in hasten is weak. " 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.
