丁二烯最大的来源是裂解乙烯厂的碳四副产物经抽提获取,其产量占全球总产量的95%。作为重要的基础石化产品的“三烯”之一,丁二烯用途非常广泛,主要用于丁苯橡胶、顺丁橡胶、丁腈橡胶等合成橡胶以及ABS、SBS等树脂塑料。未来几年,虽然丁二烯供应比较紧张,但由于天然橡胶对合成橡胶的替代作用压制了合成橡胶的价格,进而也会给丁二烯市场带来一定压力。
The largest source of butadiene is the carbon tetrachloride by-product of cracked ethylene plant, which accounts for 95% of the global output. As one of the important basic petrochemical products, “Triene” is one of the most widely used butadiene. It is mainly used in synthetic rubbers such as styrene-butadiene rubber, butadiene rubber and nitrile rubber, and plastic resins such as ABS and SBS. In the next few years, although the supply of butadiene is relatively tight, the price of synthetic rubber will be suppressed due to the substitution of natural rubber for synthetic rubber, which in turn will put some pressure on the butadiene market.
