Laperos GF30 vs Laperos HH
Polymer · Laperos grade comparison
Laperos GF30 and Laperos HH are two grades of the same polymer grade, Laperos: GF30 (30% glass-fiber reinforced) versus HH (high-heat series). 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 150 MPa (21.8 ksi) for Laperos HH, about 10% more. Laperos GF30 is the more ductile: elongation 2.5% versus 1.8% for Laperos HH. Laperos HH is stiffer (15 GPa vs 14 GPa) and Laperos HH runs hotter in service (240°C vs 220°C continuous).
Laperos GF30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Laperos HHChoose it when the part sees heat.
Laperos GF30 vs Laperos HH: 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 GF30 vs Laperos HH — frequently asked
Is Laperos GF30 stronger than Laperos HH?
Yes. Laperos GF30 has a typical tensile strength of 165 MPa (23.9 ksi) against 150 MPa (21.8 ksi) for Laperos HH — about 10% more.
Which grade does FabDigit quote by default, GF30 or HH?
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 welds better, Laperos GF30 or Laperos HH?
Laperos GF30. Its weldability rates poor (25/100) against poor (20/100) for Laperos HH.
