Laperos GF30 vs Laperos LD-RF

Polymer · Laperos grade comparison

Laperos GF30 and Laperos LD-RF are two grades of the same polymer grade, Laperos: GF30 (30% glass-fiber reinforced) versus LD-RF (low-dielectric / high-frequency grade). 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 LD-RF, about 10% more. Laperos GF30 is the more ductile: elongation 2.5% versus 2% for Laperos LD-RF. Laperos LD-RF is lighter (1.55 g/cm³ vs 1.61 g/cm³ for Laperos GF30) and Laperos GF30 is stiffer (14 GPa vs 12 GPa).

Laperos GF30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.

Laperos LD-RFChoose it when weight is the constraint.

Laperos GF30 vs Laperos LD-RF — frequently asked

Is Laperos GF30 stronger than Laperos LD-RF?

Yes. Laperos GF30 has a typical tensile strength of 165 MPa (23.9 ksi) against 150 MPa (21.8 ksi) for Laperos LD-RF — about 10% more.

Which grade does FabDigit quote by default, GF30 or LD-RF?

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.

When should I choose Laperos GF30 over Laperos LD-RF?

Pick Laperos GF30 when strength drives the design, or when the part is bent, formed or impact-loaded. Pick Laperos LD-RF when weight is the constraint.
