MF vs MF Moulding Compound
Polymer · grade comparison
MF and MF Moulding Compound are both polymer grades. MF is the stronger of the two: tensile strength 70 MPa (10.2 ksi) against 62 MPa (8.99 ksi) for MF Moulding Compound, about 13% more. MF is the more ductile: elongation 0.8% versus 0.7% for MF Moulding Compound. MF is stiffer (9 GPa vs 8.5 GPa) and MF conducts heat better (0.4 W/m·K vs 0.3 W/m·K).
MFChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
MF vs MF Moulding Compound: 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 vs MF Moulding Compound — frequently asked
Is MF stronger than MF Moulding Compound?
Yes. MF has a typical tensile strength of 70 MPa (10.2 ksi) against 62 MPa (8.99 ksi) for MF Moulding Compound — about 13% more.
Which is cheaper, MF or MF Moulding Compound?
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 or MF Moulding Compound?
MF Moulding Compound, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for MF.
