The following process conditions were set up during the extrusion runs: feed rate from 16 to 24 kg/h, water rate from 8.2% to 22%
and screw speed from 330 to 332 rpm. Material temperature, barrel pressure and torque were monitored during each of the experimental runs. The material temperature varied from 146 C to
150 C, torque from 24% to 40% and pressure from 150psi to
565psi.
