ldpe the gap between the &the must be widened to oid reducing the output due to the high back pressure&the melt fracture. the general gap sizes of ldpe&lldpe are o.024 - 0.040 in.&0.060 - 0.10in, respectively.

pp the production process of polypropylene copolymer can be divided into two kinds according to the different catalysts. one is metallocene catalyst, the other is an improved ziegler-natta efficient catalyst. the metallocene catalyst has only one active cct compared with the ziegler-natta catalyst, while the ziegler-natta catalyst has multiple active sites. metallocene catalysts can precisely control molecular weight&its distribution, the content of monomer&its distribution&crystal structure on polymer chains. the application of ziegler-natta catalyst in pp copolymerization is characterized by production process, low energy consumption, high molecular nucleation&polymer performance.
