备注说明 | Polybutene-1 (PB-1) grade Toppyl PB 8340M is a random copolymer of butene-1 with low ethylene content.In blends with PE polymers, it forms a separate, but well-dispersed phase. Its primary use is as a minority blend component in the seal layer of easy-opening packaging films, produced by cast film extrusion. A typical PE blend partner forToppyl PB 8340M could be any ethylene homo-or copolymer in the melt index range of 2.0 to 8.0 g/10min.PB-1 is also highly compatible with polypropylene due to its similar molecular structure, and it can be used to modify PP sealing behavior or mechanical properties such as impact strength. PB-1 crystallizes slowly and is very shear sensitive in its flow behavior. |
