MF Moulding Compound vs UF
Polymer · grade comparison
MF Moulding Compound and UF are both polymer grades. UF is the more ductile: elongation 0.8% versus 0.7% for MF Moulding Compound. UF is stiffer (9 GPa vs 8.5 GPa) and MF Moulding Compound runs hotter in service (130°C vs 75°C continuous).
MF Moulding CompoundChoose it when the part sees heat.
UFChoose it when the part is bent, formed or impact-loaded.
MF Moulding Compound vs UF: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer 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.

MF Moulding Compound vs UF — frequently asked
What is the difference between MF Moulding Compound and UF?
MF Moulding Compound and UF are both polymer grades. UF is the more ductile: elongation 0.8% versus 0.7% for MF Moulding Compound. UF is stiffer (9 GPa vs 8.5 GPa) and MF Moulding Compound runs hotter in service (130°C vs 75°C continuous).
Which is cheaper, MF Moulding Compound or UF?
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, MF Moulding Compound or UF?
MF Moulding Compound, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for UF.
