Polybutene-1 grade PB 8640M 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 blown film extrusion. A typical PE blend partner for PB 8640M could be any ethylene homo-or copolymer in the melt index range of 0.7 to 2.0 g/10min. Polybutene-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. Food law compliance information about this product can be found in separate product documentation. |
