聚丙烯是一种适用性很广的聚合物,它正在取代硫酸而成为工业界的“晴雨表”.聚丙烯应用于众多的工业部门,因此即使它在某一工业中的应用减少,也可以由在另一个工业部门的应用迅速增长而得到补偿.例如:汽车工业使用聚丙烯作保险杠、车内装饰件和蓄电池外壳;而建房市场使用它作地毯;食品工业使用它作板条箱和透明包装膜;余暇工业使用聚丙烯作休闲服装,而花匠利用它作花盆和绳网.因此聚丙烯的需求情况能从另一侧面反映一个国家的人均国内生产总值水平.
Polypropylene is a very versatile polymer that is replacing sulfuric acid to become a “barometer” of the industry. Polypropylene is used in a wide range of industrial sectors, so even if its use in a given industry is reduced, For example, the automotive industry uses polypropylene for bumpers, interior trim and battery housings, while the housing market uses it as a carpet, and the food industry uses it as a crate And transparent packaging film; leisure industry to use polypropylene for casual wear, and gardeners use it for pots and rope nets, so the demand for polypropylene from one side reflect the per capita gross domestic product of a country.
