PU-HighTemp vs PU-Nylon-like
Polyurethane · grade comparison
PU-HighTemp and PU-Nylon-like are both polyurethane grades. PU-HighTemp is the stronger of the two: tensile strength 65 MPa (9.43 ksi) against 55 MPa (7.98 ksi) for PU-Nylon-like, about 18% more. In exchange, PU-Nylon-like is the more ductile: elongation 25% versus 8% for PU-HighTemp. PU-HighTemp is stiffer (2.6 GPa vs 1.9 GPa) and PU-HighTemp runs hotter in service (110°C vs 80°C continuous).
PU-HighTempChoose it when strength drives the design, or when the part sees heat.
PU-Nylon-likeChoose it when the part is bent, formed or impact-loaded.
PU-HighTemp vs PU-Nylon-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-Nylon-like — frequently asked
Is PU-HighTemp stronger than PU-Nylon-like?
Yes. PU-HighTemp has a typical tensile strength of 65 MPa (9.43 ksi) against 55 MPa (7.98 ksi) for PU-Nylon-like — about 18% more.
Which is cheaper, PU-HighTemp or PU-Nylon-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.
When should I choose PU-HighTemp over PU-Nylon-like?
Pick PU-HighTemp when strength drives the design, or when the part sees heat. Pick PU-Nylon-like when the part is bent, formed or impact-loaded.
