Pressure Profile in Annular Die using PP/CO 2 Solution Viscosity
Source abstract
Abstract
In this paper, a rheological die with a rectangular channel was designed to determine the solution viscosity of supercritical CO 2 in non-crosslinked high-melt-strength (HMS) polypropylene (PP). The shear viscosity of this solution was modeled as a function of temperature, pressure, gas content, and shear rate. With interest in producing highly-expanded foamed wire coatings using an annular die, an analysis of the annular die pressure profile using the measured viscosity data and an analytical method was also conducted.
