DAIP vs PF
Polymer · grade comparison
DAIP and PF are both polymer grades. DAIP is the stronger of the two: tensile strength 55 MPa (7.98 ksi) against 52 MPa (7.54 ksi) for PF, about 6% more. PF is lighter (1.4 g/cm³ vs 1.8 g/cm³ for DAIP) and DAIP is stiffer (11 GPa vs 7 GPa). On the shop floor, PF machines more easily (good vs fair) and PF sits in a lower cost tier (standard, $$) than DAIP (high, $$$$).
DAIPChoose it when strength drives the design, or when the part sees heat.
PFChoose it when weight is the constraint, or when the part is machined in volume.
DAIP vs PF: 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.

DAIP vs PF — frequently asked
Is DAIP stronger than PF?
Yes. DAIP has a typical tensile strength of 55 MPa (7.98 ksi) against 52 MPa (7.54 ksi) for PF — about 6% more.
Which is cheaper, DAIP or PF?
PF is the lower-cost material: it sits in the standard tier ($$) while DAIP is high ($$$$). 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, DAIP or PF?
PF. Its machinability rates good (60/100) against fair (40/100) for DAIP.
