Aurum PD450 CF30 vs Aurum PD450 ESD
Polymer · Aurum PD450 grade comparison
Aurum PD450 CF30 and Aurum PD450 ESD are two grades of the same polymer grade, Aurum PD450: CF30 (30% carbon-fiber reinforced) versus ESD (ESD / static-dissipative carbon-filled grade). The chemistry is identical, so every difference below comes from the condition. Aurum PD450 CF30 is the stronger of the two: tensile strength 205 MPa (29.7 ksi) against 110 MPa (16 ksi) for Aurum PD450 ESD, about 86% more. In exchange, Aurum PD450 ESD is the more ductile: elongation 3% versus 1.8% for Aurum PD450 CF30. Aurum PD450 CF30 is stiffer (18 GPa vs 6.5 GPa) and Aurum PD450 CF30 conducts heat better (0.8 W/m·K vs 0.6 W/m·K). On the shop floor, Aurum PD450 ESD machines more easily (50 vs 40 out of 100) and Aurum PD450 CF30 welds better (45 vs 35 out of 100).
Aurum PD450 CF30Choose it when strength drives the design, or when it will be welded.
Aurum PD450 ESDChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Aurum PD450 CF30 vs Aurum PD450 ESD: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
