ABS-ESD vs Stratasys PC-ISO

Polymer · grade comparison

ABS-ESD and PC-ISO are both polymer grades, both specialty plastic. PC-ISO is the stronger of the two: yield strength 52 MPa (7.54 ksi) against 34 MPa (4.93 ksi) for ABS-ESD, about 53% more; tensile strength follows at 57 MPa (8.27 ksi) vs 36 MPa (5.22 ksi). PC-ISO is the more ductile: elongation 4.3% versus 3% for ABS-ESD, and PC-ISO is harder (80 Shore D vs 76 Shore D). ABS-ESD is lighter (1.04 g/cm³ vs 1.2 g/cm³ for PC-ISO) and ABS-ESD is stiffer (2.4 GPa vs 2 GPa). On the shop floor, ABS-ESD sits in a lower cost tier (premium, $$$) than PC-ISO (high, $$$$).
