PC-Medical ESD vs PC-Medical GF30
Polymer · PC-Medical grade comparison
PC-Medical ESD and PC-Medical GF30 are two grades of the same polymer grade, PC-Medical: ESD (static-dissipative medical PC) versus GF30 (30% glass-fiber reinforced medical PC). The chemistry is identical, so every difference below comes from the condition. PC-Medical GF30 is the stronger of the two: tensile strength 125 MPa (18.1 ksi) against 62 MPa (8.99 ksi) for PC-Medical ESD, about 102% more. In exchange, PC-Medical ESD is the more ductile: elongation 15% versus 3% for PC-Medical GF30. PC-Medical ESD is lighter (1.2 g/cm³ vs 1.43 g/cm³ for PC-Medical GF30) and PC-Medical GF30 is stiffer (7.5 GPa vs 2.8 GPa). On the shop floor, PC-Medical ESD machines more easily (good vs fair) and PC-Medical GF30 welds better (very good vs fair).
PC-Medical ESDChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
PC-Medical GF30Choose it when strength drives the design, or when it will be welded.
PC-Medical ESD vs PC-Medical GF30: 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.
