About this Review
This technical review supports engineering evaluation of polycarbonate reclaim strategies in regulated injection molding environments, drawing on peer-reviewed polymer-processing literature, including published data on heat history and molecular-weight retention during repeated extrusion and injection molding cycles. The discussion is comparative and risk-based rather than prescriptive, examining how reclaim form and processing approach influence thermal exposure, degradation mechanisms, and process robustness within established quality systems and validation frameworks.
“When properly controlled, the process-stability and scrap-reduction benefits of re-pelletizing can outweigh the modest additional thermal exposure it introduces.”
