ABS-Like FR vs PC-Like
Polyurethane · grade comparison
ABS-Like FR and PC-Like are both polyurethane grades, both rigid pu. PC-Like is the stronger of the two: yield strength 52 MPa (7.54 ksi) against 45 MPa (6.53 ksi) for ABS-Like FR, about 16% more; tensile strength follows at 60 MPa (8.7 ksi) vs 50 MPa (7.25 ksi). PC-Like is stiffer (2.7 GPa vs 2.3 GPa) and ABS-Like FR runs hotter in service (70°C vs 60°C continuous). On the shop floor, ABS-Like FR machines more easily (very good vs good).
ABS-Like FRChoose it when the part sees heat, or when the part is machined in volume.
PC-LikeChoose it when strength drives the design.
ABS-Like FR vs 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.

ABS-Like FR vs PC-Like — frequently asked
Is PC-Like stronger than ABS-Like FR?
Yes. PC-Like has a typical yield strength of 52 MPa (7.54 ksi) against 45 MPa (6.53 ksi) for ABS-Like FR — about 16% more. Tensile strength is 60 MPa (8.7 ksi) vs 50 MPa (7.25 ksi).
Which is cheaper, ABS-Like FR or PC-Like?
Both sit in the same relative cost tier ($$, standard); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, ABS-Like FR or PC-Like?
ABS-Like FR. Its machinability rates very good (75/100) against good (58/100) for PC-Like.
