主要应用领域Major End Use：沥青改性Bitumen modification。
供应情况Supply situation：主要用于沥青改性，道路施工、防水卷材等，一般需求量较大。每年5月-10月是需求旺季。为了缓解夏季供应不足，多数供应商和使用单位在11月-2月进行冬储。少量有现货供应，量大需预定。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.
