PU-GF-Filled vs PU-PC-like
Polyurethane · grade comparison
PU-GF-Filled and PU-PC-like are both polyurethane grades. PU-PC-like is the more ductile: elongation 12% versus 2.5% for PU-GF-Filled, and PU-GF-Filled is harder (87 Shore D vs 82 Shore D). PU-PC-like is lighter (1.13 g/cm³ vs 1.55 g/cm³ for PU-GF-Filled) and PU-GF-Filled is stiffer (5.5 GPa vs 2.2 GPa).
PU-GF-FilledChoose it when the part sees heat.
PU-PC-likeChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
PU-GF-Filled 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-GF-Filled vs PU-PC-like — frequently asked
What is the difference between PU-GF-Filled and PU-PC-like?
PU-GF-Filled and PU-PC-like are both polyurethane grades. PU-PC-like is the more ductile: elongation 12% versus 2.5% for PU-GF-Filled, and PU-GF-Filled is harder (87 Shore D vs 82 Shore D). PU-PC-like is lighter (1.13 g/cm³ vs 1.55 g/cm³ for PU-GF-Filled) and PU-GF-Filled is stiffer (5.5 GPa vs 2.2 GPa).
Which is cheaper, PU-GF-Filled 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-GF-Filled or PU-PC-like?
PU-PC-like, by a small margin. Both rate good for machinability — 65/100 against 60/100 for PU-GF-Filled; for welding the order is PU-GF-Filled first (not recommended, 5/100) then PU-PC-like (not recommended, 0/100).
