ABS-Like FR vs GF Nylon-Like
Polyurethane · grade comparison
ABS-Like FR and GF Nylon-Like are both polyurethane grades, both rigid pu. GF Nylon-Like is the stronger of the two: tensile strength 60 MPa (8.7 ksi) against 50 MPa (7.25 ksi) for ABS-Like FR, about 20% more. In exchange, ABS-Like FR is the more ductile: elongation 9% versus 5% for GF Nylon-Like. ABS-Like FR is lighter (1.17 g/cm³ vs 1.4 g/cm³ for GF Nylon-Like) and GF Nylon-Like is stiffer (4 GPa vs 2.3 GPa). On the shop floor, ABS-Like FR machines more easily (very good vs good).
ABS-Like FRChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
GF Nylon-LikeChoose it when strength drives the design, or when the part sees heat.
ABS-Like FR vs GF 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.

ABS-Like FR vs GF Nylon-Like — frequently asked
Is GF Nylon-Like stronger than ABS-Like FR?
Yes. GF Nylon-Like has a typical tensile strength of 60 MPa (8.7 ksi) against 50 MPa (7.25 ksi) for ABS-Like FR — about 20% more.
Which is cheaper, ABS-Like FR or GF Nylon-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 GF Nylon-Like?
ABS-Like FR. Its machinability rates very good (75/100) against good (55/100) for GF Nylon-Like.
