PU-HighTemp vs PU-PC-like
Polyurethane · grade comparison
PU-HighTemp and PU-PC-like are both polyurethane grades. PU-HighTemp is the stronger of the two: tensile strength 65 MPa (9.43 ksi) against 60 MPa (8.7 ksi) for PU-PC-like, about 8% more. In exchange, PU-PC-like is the more ductile: elongation 12% versus 8% for PU-HighTemp. PU-HighTemp is stiffer (2.6 GPa vs 2.2 GPa) and PU-HighTemp runs hotter in service (110°C vs 70°C continuous).
PU-HighTempChoose it when strength drives the design, or when the part sees heat.
PU-PC-likeChoose it when the part is bent, formed or impact-loaded.
PU-HighTemp vs PU-PC-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-PC-like — frequently asked
Is PU-HighTemp stronger than PU-PC-like?
Yes. PU-HighTemp has a typical tensile strength of 65 MPa (9.43 ksi) against 60 MPa (8.7 ksi) for PU-PC-like — about 8% more.
Which is cheaper, PU-HighTemp or PU-PC-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-PC-like?
PU-HighTemp. Its machinability rates very good (70/100) against good (65/100) for PU-PC-like.
