34 Properties - Stress Relaxation Stress Relaxation Comparison of PC & Just after injection 60 12hrs hrs 5 Just after injection 60 12hrs 90 5hrs PC Creative product design is very important in choosing plastic material. After thermoforming or other secondary fabrication, a complicated part may retain residual stress. If residual stresses are not adequately removed, PC has been known to form small cracks due to environmental stress cracking.
