PU-HighTemp vs PU-PMMA-like
Polyurethane · grade comparison
PU-HighTemp and PU-PMMA-like are both polyurethane grades. PU-PMMA-like is the more ductile: elongation 10% versus 8% for PU-HighTemp. PU-HighTemp runs hotter in service (110°C vs 70°C continuous).
PU-HighTempChoose it when the part sees heat.
PU-PMMA-likeChoose it when the part is bent, formed or impact-loaded.
PU-HighTemp 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-HighTemp vs PU-PMMA-like — frequently asked
What is the difference between PU-HighTemp and PU-PMMA-like?
PU-HighTemp and PU-PMMA-like are both polyurethane grades. PU-PMMA-like is the more ductile: elongation 10% versus 8% for PU-HighTemp. PU-HighTemp runs hotter in service (110°C vs 70°C continuous).
Which is cheaper, PU-HighTemp 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-HighTemp or PU-PMMA-like?
PU-PMMA-like, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for PU-HighTemp.
