主要應(yīng)用領(lǐng)域Major End Use：瀝青改性Bitumen modification。


供應(yīng)情況Supply situation：主要用于瀝青改性，道路施工、防水卷材等，一般需求量較大。每年5月-10月是需求旺季。為了緩解夏季供應(yīng)不足，多數(shù)供應(yīng)商和使用單位在11月-2月進(jìn)行冬儲(chǔ)。少量有現(xiàn)貨供應(yīng)，量大需預(yù)定。The utility model is mainly used for asphalt modification, road construction, waterproof coiled material and so on. May -10 months is the peak season demand. In order to ease the supply shortage in summer, the majority of suppliers and the use of units in November -2 months for winter storage. A small number of spot supply, the amount of large reservations.
