PP-H GF40 vs PP-H HP PP
Polymer · PP-H grade comparison
PP-H GF40 and HP 3D High Reusability PP (enabled by Forward AM / BASF) are two grades of the same polymer grade, PP-H: GF40 (40 % coupled glass-fiber reinforced PP homopolymer) versus HP PP. The chemistry is identical, so every difference below comes from the condition. PP-H GF40 is the stronger of the two: tensile strength 105 MPa (15.2 ksi) against 30 MPa (4.35 ksi) for HP 3D High Reusability PP (enabled by Forward AM / BASF), about 3.5 times as much. In exchange, HP 3D High Reusability PP (enabled by Forward AM / BASF) is the more ductile: elongation 20% versus 2.5% for PP-H GF40. HP 3D High Reusability PP (enabled by Forward AM / BASF) is lighter (0.89 g/cm³ vs 1.22 g/cm³ for PP-H GF40) and PP-H GF40 is stiffer (8.5 GPa vs 1.6 GPa).
PP-H GF40Choose it when strength drives the design.
HP 3D High Reusability PP (enabled by Forward AM / BASF)Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
PP-H GF40 vs HP 3D High Reusability PP (enabled by Forward AM / BASF): 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.

PP-H GF40 vs HP 3D High Reusability PP (enabled by Forward AM / BASF) — frequently asked
Is PP-H GF40 stronger than HP 3D High Reusability PP (enabled by Forward AM / BASF)?
Yes. PP-H GF40 has a typical tensile strength of 105 MPa (15.2 ksi) against 30 MPa (4.35 ksi) for HP 3D High Reusability PP (enabled by Forward AM / BASF) — about 3.5 times as much.
Which grade does FabDigit quote by default, GF40 or HP PP?
UNF is the default PP-H condition in the FabDigit quote flow (neither GF40 nor HP PP). 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 PP-H GF40 over HP 3D High Reusability PP (enabled by Forward AM / BASF)?
Pick PP-H GF40 when strength drives the design. Pick HP 3D High Reusability PP (enabled by Forward AM / BASF) when the part is bent, formed or impact-loaded, or when weight is the constraint.
