PU-FR-V0 vs PU-PMMA-like
Polyurethane · grade comparison
PU-FR-V0 and PU-PMMA-like are both polyurethane grades. PU-PMMA-like is the stronger of the two: tensile strength 65 MPa (9.43 ksi) against 48 MPa (6.96 ksi) for PU-FR-V0, about 35% more. PU-PMMA-like is the more ductile: elongation 10% versus 6% for PU-FR-V0. PU-PMMA-like is lighter (1.13 g/cm³ vs 1.6 g/cm³ for PU-FR-V0) and PU-FR-V0 runs hotter in service (80°C vs 70°C continuous). On the shop floor, PU-PMMA-like machines more easily (very good vs good).
PU-FR-V0Choose it when the part sees heat.
PU-PMMA-likeChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
PU-FR-V0 vs PU-PMMA-like: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polyurethane 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.

PU-FR-V0 vs PU-PMMA-like — frequently asked
Is PU-PMMA-like stronger than PU-FR-V0?
Yes. PU-PMMA-like has a typical tensile strength of 65 MPa (9.43 ksi) against 48 MPa (6.96 ksi) for PU-FR-V0 — about 35% more.
Which is cheaper, PU-FR-V0 or PU-PMMA-like?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, PU-FR-V0 or PU-PMMA-like?
PU-PMMA-like. Its machinability rates very good (75/100) against good (65/100) for PU-FR-V0; for welding the order is PU-PMMA-like first (not recommended, 5/100) then PU-FR-V0 (not recommended, 0/100).
