LCP Type III GF30 vs LCP Type III GFMF
Polymer · LCP Type III grade comparison
LCP Type III GF30 and LCP Type III GFMF are two grades of the same polymer grade, LCP Type III: GF30 (30 % glass-fibre reinforced) versus GFMF (GF/MF hybrid). The chemistry is identical, so every difference below comes from the condition. LCP Type III GF30 is the stronger of the two: tensile strength 160 MPa (23.2 ksi) against 130 MPa (18.9 ksi) for LCP Type III GFMF, about 23% more. LCP Type III GF30 is the more ductile: elongation 1.8% versus 1.6% for LCP Type III GFMF. LCP Type III GF30 is lighter (1.62 g/cm³ vs 1.7 g/cm³ for LCP Type III GFMF) and LCP Type III GFMF runs hotter in service (200°C vs 180°C continuous). On the shop floor, LCP Type III GF30 welds better (30 vs 20 out of 100).
LCP Type III GF30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
LCP Type III GFMFChoose it when the part sees heat.
LCP Type III GF30 vs LCP Type III GFMF: 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 Type III GF30 vs LCP Type III GFMF — frequently asked
Is LCP Type III GF30 stronger than LCP Type III GFMF?
Yes. LCP Type III GF30 has a typical tensile strength of 160 MPa (23.2 ksi) against 130 MPa (18.9 ksi) for LCP Type III GFMF — about 23% more.
Which grade does FabDigit quote by default, GF30 or GFMF?
Specify the condition in the material field or the drawing note; FabDigit prices the quote for the state you call out.
Which is easier to machine, LCP Type III GF30 or LCP Type III GFMF?
LCP Type III GF30, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for LCP Type III GFMF; for welding the order is LCP Type III GF30 first (poor, 30/100) then LCP Type III GFMF (poor, 20/100).
