My. Lyu et Jl. White, RESIDENCE TIME DISTRIBUTIONS AND BASIC STUDIES OF FLOW AND MELTING INA MODULAR BUSS-KNEADER, Polymer engineering and science, 38(9), 1998, pp. 1366-1377
Experimental studies of residence time distribution, fill factor, temp
erature, and melting profiles of thermoplastic resins are presented. R
esidence time distributions were determined as a function of throughpu
t and screw speed. The melting of polypropylene and low density polyet
hylene in the entrance region was investigated. Fill factor and temper
ature profiles are reported.
