Speed up the pace of engineering technological innovation and realize high performance for general-purpose synthetic resins

摘要

Synthetic resins normally refer to polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) and copolymer of acrylonitrile-butadiene-styreen (ABS). The consumption quantity and the degree of high performance of generic synthetic resins are an important sign of the development of a nation. In the past twenty years, the annual porduction of steal remained around 750 million tons while the annual production of synthetic resin has increased by three times and reached 139 million tons in 1997, exceeding steal production if compared by volume. The continuous increase of the GDP of China brings a two-digit increase in annual generic resin consumption, which initiates huge resin import that reached 6.4 million tons in 1999, accounting for roughly 50
