Laperos ESD vs Laperos GF30
Polymer · Laperos grade comparison
Laperos ESD and Laperos GF30 are two grades of the same polymer grade, Laperos: ESD (ESD / conductive) versus GF30 (30% glass-fiber reinforced). The chemistry is identical, so every difference below comes from the condition. Laperos GF30 is the stronger of the two: tensile strength 165 MPa (23.9 ksi) against 145 MPa (21 ksi) for Laperos ESD, about 14% more. Laperos GF30 is the more ductile: elongation 2.5% versus 1.6% for Laperos ESD. Laperos ESD is stiffer (16 GPa vs 14 GPa) and Laperos ESD conducts heat better (0.8 W/m·K vs 0.35 W/m·K).
Laperos GF30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Laperos ESD vs Laperos 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.

Laperos ESD vs Laperos GF30 — frequently asked
Is Laperos GF30 stronger than Laperos ESD?
Yes. Laperos GF30 has a typical tensile strength of 165 MPa (23.9 ksi) against 145 MPa (21 ksi) for Laperos ESD — about 14% more.
Which grade does FabDigit quote by default, ESD or GF30?
GF30 is the default Laperos condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, Laperos ESD or Laperos GF30?
Laperos GF30. Its machinability rates fair (40/100) against poor (34/100) for Laperos ESD.
