ABS-Like vs ABS-Like FR
Polyurethane · grade comparison
ABS-Like and ABS-Like FR are both polyurethane grades, both rigid pu. Both yield at about 45 MPa — strength does not separate them. ABS-Like is the more ductile: elongation 12% versus 9% for ABS-Like FR. ABS-Like is lighter (1.12 g/cm³ vs 1.17 g/cm³ for ABS-Like FR) and ABS-Like FR runs hotter in service (70°C vs 55°C continuous). On the shop floor, ABS-Like FR machines more easily (very good vs good) and ABS-Like sits in a lower cost tier (budget, $) than ABS-Like FR (standard, $$).
ABS-LikeChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
ABS-Like FRChoose it when the part sees heat, or when the part is machined in volume.
ABS-Like vs ABS-Like FR: 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 vs ABS-Like FR — frequently asked
What is the difference between ABS-Like and ABS-Like FR?
ABS-Like and ABS-Like FR are both polyurethane grades, both rigid pu. Both yield at about 45 MPa — strength does not separate them. ABS-Like is the more ductile: elongation 12% versus 9% for ABS-Like FR.
Which is cheaper, ABS-Like or ABS-Like FR?
ABS-Like is the lower-cost material: it sits in the budget tier ($) while ABS-Like FR is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, ABS-Like or ABS-Like FR?
ABS-Like FR. Its machinability rates very good (75/100) against good (55/100) for ABS-Like; for welding the order is ABS-Like FR first (not recommended, 10/100) then ABS-Like (not recommended, 5/100).
