Aurum PD450 ESD vs Aurum PD450 GF30

Polymer · Aurum PD450 grade comparison

Aurum PD450 ESD and Aurum PD450 GF30 are two grades of the same polymer grade, Aurum PD450: ESD (ESD / static-dissipative carbon-filled grade) versus GF30 (30% glass-fiber reinforced). The chemistry is identical, so every difference below comes from the condition. Aurum PD450 GF30 is the stronger of the two: tensile strength 165 MPa (23.9 ksi) against 110 MPa (16 ksi) for Aurum PD450 ESD, about 50% more. In exchange, Aurum PD450 ESD is the more ductile: elongation 3% versus 2.5% for Aurum PD450 GF30. Aurum PD450 ESD is lighter (1.42 g/cm³ vs 1.55 g/cm³ for Aurum PD450 GF30) and Aurum PD450 GF30 is stiffer (9.5 GPa vs 6.5 GPa). On the shop floor, Aurum PD450 GF30 welds better (45 vs 35 out of 100).
