PC-ABS ESD vs PC-ABS GF30

Polymer · PC-ABS grade comparison

PC-ABS ESD and PC-ABS GF30 are two grades of the same polymer grade, PC-ABS: ESD (antistatic / conductive) versus GF30 (30% glass-fiber reinforced). The chemistry is identical, so every difference below comes from the condition. PC-ABS GF30 is the stronger of the two: yield strength 55 MPa (7.98 ksi) against 52 MPa (7.54 ksi) for PC-ABS ESD, about 6% more; tensile strength follows at 115 MPa (16.7 ksi) vs 52 MPa (7.54 ksi). In exchange, PC-ABS ESD is the more ductile: elongation 20% versus 2.5% for PC-ABS GF30. PC-ABS ESD is lighter (1.18 g/cm³ vs 1.35 g/cm³ for PC-ABS GF30) and PC-ABS GF30 is stiffer (7.5 GPa vs 2.7 GPa). On the shop floor, PC-ABS ESD machines more easily (good vs fair) and PC-ABS GF30 welds better (very good vs fair).
