发泡聚苯乙烯粒子当初是由西德的BASF 公司向日本进口,然后再进行成形加工,如此已约25年。当初作为保冷材料,用于冷冻船、冷冻冷藏仓库等,进而作为家庭电器产品的缓冲包装材料及种种需要飞速扩大使用了。发泡聚苯乙烯成形物的组成大约由98%的空气促成。所以当塑料受到第一次石油打击后,在节约资源的年代得以克服、并迅速恢复。随着鱼箱、绝热材料等需要的扩大而不断增长,以至日本聚苯乙烯的使用量已超过10万吨的巨数。(见表1) Styrofoam particles were originally imported from Japan by BASF of West Germany and were then shaped for about 25 years. Originally used as a cold-proof material, used in frozen ships, refrigerated warehouses, etc., and then as a household electrical appliances, cushioning packaging materials and the need to rapidly expand the use of. The composition of the expanded polystyrene moldings is contributed by about 98% of the air. So after the first oil crackdown on plastic, the era of resource conservation was overcome and the economy recovered quickly. With the expansion of fish boxes, insulation materials and other needs continue to grow, as the use of polystyrene in Japan has more than 100,000 tons of giant. (See Table 1)
