TYPICAL ABS PROCESSING:
CONDITIONS DRYING: it is recommended that GBPC ABS Resins be dried at (80-85°c)for 3 hours. The following molding conditions are recommended starting point for GBPC ABS Resin.
A moisture level of ≤0.1% should be reached before injection molding the resin.
Some modifications may be required depending on the specific molding equipment and part configuration.
