The Effect of Injection Moulding Processing Parameters on the Environmental Stress Cracking Resistance of Polycarbonate Mouldings,

Abstract

The effect of injection moulding processing variables on the environmental stress cracking performance of polycarbonate grades 121 and 101 has been studied. Grade 121 is a general purpose easy flowing grade whilst grade 101 is a high viscosity, high molecular weight grade. A solution of 50:50 by volume toluene/iso-octane was applied as a stress cracking agent and a tensile impact tester was used to determine the strength of the mouldings after immersion in the solvent.
