Adjacent benzene is general-purpose colophony - 450, double-loop (DC) the hand papers colophony - 590, man-made stone / stone stone colophony - 420, pull crowded colophony - 460, twine structural layer colophony - 510, twine a benzene liner colophony - 730, colophony of NPG mould pressing - 560, colophony of DPG mould pressing - 890. Raw material market glides continuously, colophony market price continues to reduce 300 yuan considerably- - 500 yuan. Early days of this continuance of market of week raw material glides situation condition, especially early days rises the breed with vast range, for example third is 2 alcohol, suitable anhydride, styrene gets stock prices of inferior influence occurrence concussion. At present UPR market is in relatively difficult unfavorable situation, start working of entire industry whole is led already under 50% . Main effect comes from two respects, because raw material has risen in price,one is downstream project project fast, capital is used up exceed a budget, partial project already level sex shutdown; Another is the influence of Guangdong epidemic situation, the keep long in stock of Shenzhen saline harbor that regards international shipping as the hub export container in great quantities, this haven day all handles the 1/7 that the ability of container has dropped to be measured normally, the stone stone outlet that gives Huanade the division causes tremendous effect, plant of production of stone of a lot of quartz piled up to need product of exit quartz stone in great quantities, if short-term inside cannot get solve, these stone stone factories can be forced only stop production, force UPR shop thereby substantially reduction of output or level sex stop production. Last as heavy goods price fall after a rise, predict the start working circumstance of factory of northern region UPR end June to will get preliminary improvement likely, and after southern region needs to await international shipping to return to normal, ability restores subsequently. Accordingly on the whole, at present of UPR market low confuse condition to will still last for some time. " 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.
