LCP-MF vs LCP Type III
Polymer · grade comparison
LCP-MF and LCP Type III are both polymer grades. LCP Type III is the stronger of the two: tensile strength 150 MPa (21.8 ksi) against 115 MPa (16.7 ksi) for LCP-MF, about 30% more. LCP Type III is the more ductile: elongation 3% versus 2% for LCP-MF. LCP Type III is lighter (1.4 g/cm³ vs 1.82 g/cm³ for LCP-MF) and LCP-MF is stiffer (11 GPa vs 10 GPa). On the shop floor, LCP Type III machines more easily (good vs fair).
LCP-MFChoose it when the part sees heat.
LCP Type IIIChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
LCP-MF vs LCP Type III: 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.

LCP-MF vs LCP Type III — frequently asked
Is LCP Type III stronger than LCP-MF?
Yes. LCP Type III has a typical tensile strength of 150 MPa (21.8 ksi) against 115 MPa (16.7 ksi) for LCP-MF — about 30% more.
Which is cheaper, LCP-MF or LCP Type III?
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, LCP-MF or LCP Type III?
LCP Type III. Its machinability rates good (55/100) against fair (45/100) for LCP-MF; for welding the order is LCP Type III first (poor, 30/100) then LCP-MF (poor, 25/100).
