How Processing Conditions Affect Polycarbonate Color Consistency

Executive Overview

A recent study using a transparent polycarbonate blend and red letdown pigment found that processing temperature, screw speed, and feed rate significantly affect final color consistency by altering melt viscosity and pigment dispersion.

Manufacturing & Process Note

Color consistency in polycarbonate compounding hinges on tight control of melt temperature, screw speed, and feed rate; processors should establish a validated operating window rather than chase formulation adjustments, as excessive thermal exposure can degrade the polymer and pigment system, increasing scrap and rework.
