Toppyl PB 8340M
About this product
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 for Toppyl 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.
