Adjacent benzene is general-purpose colophony 60, double-loop (DC) the hand papers colophony 170, man-made stone / stone stone colophony 30, pull crowded colophony 40, twine structural layer colophony 70, twine a benzene liner colophony 90, colophony of NPG mould pressing 80, colophony of DPG mould pressing 170. The spurt in prices that arrange anhydride, colophony cost rises, market price of short duration is firm. This week UPR advanced position is major raw material keeps stable, but suitable anhydride price is falling half week weak point 1000 yuan of above soare between 2 climate. Because its Central Plains has multiple factor: First, the order that comes from India is fuse that rise in price, export a quantity increase those who mean amount of sale in domestic market to decrease; Next, the part arranges anhydride factory to appear to jockey temporarily, reduced market supply; The 3rd, suffer epidemic situation effect, appearance asks for suffocate suffocate of shipment of suitable anhydride factory, hua Dong area supplies pressure to increase, and the market is anxious, once Yangzhou epidemic situation continues to worsen, appearance asks for suitable anhydride factory to because carry suffocate suffocate,can have the risk that is forced to jockey. Be based on above a variety of reasons, it is under suitable anhydride factory and hype of trafficker join forces, suitable anhydride price appears to soare for an instant, and Hua Na area is exceeding be in short supply. Arrange the change of anhydride prices to this, our viewpoint is: First, indian order amount is limited, to arranging anhydride market overall situation won't produce apparent effect; Next, a few are faced stop suitable anhydride factory to resume production immediately, available supply ability is about to increase; The 3rd, yangzhou epidemic situation is getting be controllinged effectively, and pass " chemical industry signs up for " the report that tastes content to shed difficult position to chemical industry of Nanjing and Yangzhou periphery region, pertinent question hopeful gets settlement as soon as possible, the carriage problem of suitable anhydride is unlikely to can worsen further. The 4th, UPR market is very at present flat, short-term inside the sign that cannot see clear improvement, because be opposite inside this near future,the wastage of suitable anhydride can decrease only won't grow in quantity, this also is the prime cause that price of early days suitable anhydride takes low continuously; Accordingly, at present the main area of the market does not support the abidance of suitable anhydride price to go tall, market hype is put in bigger risk. Although arrange anhydride price to appear,soare, but the stability that major UPR factory still carried sale price, such doing is on one hand by force of market pressure, in downstream demand the situation of global depression falls, take the lead in rising in price have desertion the risk of the market, additional on one hand, more and more UPR factories adopted the method that reduces yield actively, avoid arranges the venture that anhydride rises in price. Of price of this round of suitable anhydride soare, aggravate UPR factory and the contradiction that arrange anhydride to produce a business partly, build suitable anhydride factory to opened the market quickly to create advantage for sequel. " 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.
