LCP CF30 vs LCP GF30
Polymer · grade comparison
LCP CF30 and LCP-GF30 are both polymer grades, compared here in the CF30 condition. LCP CF30 is the stronger of the two: tensile strength 195 MPa (28.3 ksi) against 180 MPa (26.1 ksi) for LCP-GF30, about 8% more. In exchange, LCP-GF30 is the more ductile: elongation 2.8% versus 1.2% for LCP CF30. LCP CF30 is lighter (1.53 g/cm³ vs 1.61 g/cm³ for LCP-GF30) and LCP CF30 is stiffer (27 GPa vs 15 GPa). On the shop floor, LCP-GF30 machines more easily (good vs fair) and LCP-GF30 sits in a lower cost tier (high, $$$$) than LCP CF30 (specialty, $$$$$).
LCP CF30Choose it when strength drives the design, or when weight is the constraint.
LCP-GF30Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
LCP CF30 vs LCP-GF30: 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.
