PU-ABS-like vs PU-PC-like
Polyurethane · grade comparison
PU-ABS-like and PU-PC-like are both polyurethane grades. PU-ABS-like is the stronger of the two: yield strength 55 MPa (7.98 ksi) against 50 MPa (7.25 ksi) for PU-PC-like, about 10% more. On the shop floor, PU-ABS-like machines more easily (very good vs good).
PU-ABS-likeChoose it when strength drives the design, or when the part is machined in volume.
PU-ABS-like 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-ABS-like vs PU-PC-like — frequently asked
Is PU-ABS-like stronger than PU-PC-like?
Yes. PU-ABS-like has a typical yield strength of 55 MPa (7.98 ksi) against 50 MPa (7.25 ksi) for PU-PC-like — about 10% more. Tensile strength is 60 MPa (8.7 ksi) vs 60 MPa (8.7 ksi).
Which is cheaper, PU-ABS-like 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-ABS-like or PU-PC-like?
PU-ABS-like. Its machinability rates very good (80/100) against good (65/100) for PU-PC-like.
