TPU-Ether FR-V0 vs TPU-Ether GF30
Polymer · TPU-Ether grade comparison
TPU-Ether FR-V0 and TPU-Ether GF30 are two grades of the same polymer grade, TPU-Ether: FR-V0 versus GF30 (30 % glass-fiber reinforced). The chemistry is identical, so every difference below comes from the condition. TPU-Ether GF30 is the stronger of the two: tensile strength 45 MPa (6.53 ksi) against 32 MPa (4.64 ksi) for TPU-Ether FR-V0, about 41% more. In exchange, TPU-Ether FR-V0 is the more ductile: elongation 420% versus 15% for TPU-Ether GF30, and TPU-Ether GF30 is harder (74 Shore D vs 38 Shore D). TPU-Ether FR-V0 is lighter (1.22 g/cm³ vs 1.35 g/cm³ for TPU-Ether GF30) and TPU-Ether GF30 is stiffer (2.8 GPa vs 0.04 GPa). On the shop floor, TPU-Ether GF30 machines more easily (good vs poor) and TPU-Ether GF30 welds better (excellent vs very good).
TPU-Ether FR-V0Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
TPU-Ether GF30Choose it when strength drives the design, or when the part sees heat.
TPU-Ether FR-V0 vs TPU-Ether 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.

TPU-Ether FR-V0 vs TPU-Ether GF30 — frequently asked
Is TPU-Ether GF30 stronger than TPU-Ether FR-V0?
Yes. TPU-Ether GF30 has a typical tensile strength of 45 MPa (6.53 ksi) against 32 MPa (4.64 ksi) for TPU-Ether FR-V0 — about 41% more.
Which grade does FabDigit quote by default, FR-V0 or GF30?
85A is the default TPU-Ether condition in the FabDigit quote flow (neither FR-V0 nor GF30). 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, TPU-Ether FR-V0 or TPU-Ether GF30?
TPU-Ether GF30. Its machinability rates good (55/100) against poor (30/100) for TPU-Ether FR-V0; for welding the order is TPU-Ether GF30 first (excellent, 90/100) then TPU-Ether FR-V0 (very good, 80/100).
