n (PlastiCorder®) An instrument that continuously measures the torque exerted in shearing a polymer or compound specimen over a wider range of shear rates and temperatures, including those conditions anticipated in actual processing. The instrument records torque, time and temperature with a computer generated graphical representation referred to as a plastigram, from which one can infer processability. It shows the effect of additives and fillers, measures and records lubricity, plasticity, scorch, cure, shear and heat stability, and polymer consistency. The modern instrument is equipped with interchangeable heads for bench-scale studies of mixing and extrusion, and with computer control and data acquisition.
