Investigation of flow behavior for linear melt blown polypropylenes with different molecular weights in very wide shear rate range

Popis výsledku v původním jazyce

In this work, three different linear polypropylenes, with melt flow rate between 450-1200 g.10min-1, have been characterized by using rotational and twin bore capillary rheometer equipped by novel inert orifice die design as well as by the instrumented injection molding machine. The measured data, that shows first as well as second Newtonian plateau, were consequently fitted by four conventional models (Cross, Carreau, Generalized Quemada and Carreau-Yasuda models) as well as by two novel viscosity models (modified Quemada and Carreau models) suggested here for the first time. It has been found that modified 5-parametric Carreau model has the highest capability to describe the measured shear viscosity data for given polymer melts.
