LCP-GF30 vs LCP Type I
Polymer · grade comparison
LCP-GF30 and LCP Type I are both polymer grades. LCP-GF30 is the stronger of the two: tensile strength 180 MPa (26.1 ksi) against 135 MPa (19.6 ksi) for LCP Type I, about 33% more. LCP-GF30 is the more ductile: elongation 2.8% versus 2.5% for LCP Type I. LCP Type I is lighter (1.38 g/cm³ vs 1.61 g/cm³ for LCP-GF30) and LCP-GF30 is stiffer (15 GPa vs 11 GPa).
LCP-GF30Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
LCP Type IChoose it when weight is the constraint.
LCP-GF30 vs LCP Type I: 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-GF30 vs LCP Type I — frequently asked
Is LCP-GF30 stronger than LCP Type I?
Yes. LCP-GF30 has a typical tensile strength of 180 MPa (26.1 ksi) against 135 MPa (19.6 ksi) for LCP Type I — about 33% more.
Which is cheaper, LCP-GF30 or LCP Type I?
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-GF30 or LCP Type I?
LCP Type I, by a small margin. Both rate good for machinability — 62/100 against 55/100 for LCP-GF30; for welding the order is LCP-GF30 first (poor, 25/100) then LCP Type I (poor, 20/100).
