Aim To research the influence of the sort and quantity of the rheological modifier and the polymer ingredient to the flowing property of PE with high filler content talcum. Methods The effects of the polymer ingredient and the sort and quantity of the rheological modifier on apparent viscosity are investigated. Results The rheological property of the high filler content material is influenced by the sort and quantity of the rheological modifier and the polymer ingredient. Conclusion The theoretical basis for improvving the design of the high filler content material ingredient and the further perfection of the technology are given.
