LCP GF15 vs LCP GF30
Polymer · grade comparison
LCP GF15 and LCP-GF30 are both polymer grades, compared here in the GF15 condition. LCP-GF30 is the stronger of the two: tensile strength 180 MPa (26.1 ksi) against 165 MPa (23.9 ksi) for LCP GF15, about 9% more. LCP-GF30 is the more ductile: elongation 2.8% versus 2.5% for LCP GF15. LCP GF15 is lighter (1.51 g/cm³ vs 1.61 g/cm³ for LCP-GF30) and LCP-GF30 is stiffer (15 GPa vs 12.5 GPa). On the shop floor, LCP-GF30 sits in a lower cost tier (high, $$$$) than LCP GF15 (specialty, $$$$$).
LCP GF15Choose it when weight is the constraint.
LCP-GF30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
LCP GF15 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.
