TYPICAL ABS PROCESSING:

DRYING: it is recommended that GBPC ABS Heat Resistance Resins be dried at (80-90°c)for 3 hours.

A moisture level of ≤0.1% should be reached beforeinjection molding the resin.

The following molding conditions are recommended starting point for GBPC ABS Resin.

Some modifications may be required depending on the specific molding equipment and part configuration.
