LCP-GF30 vs LCP Type II
Polymer · grade comparison
LCP-GF30 and LCP Type II are both polymer grades. LCP Type II is the more ductile: elongation 3.5% versus 2.8% for LCP-GF30. LCP Type II is lighter (1.4 g/cm³ vs 1.61 g/cm³ for LCP-GF30) and LCP-GF30 is stiffer (15 GPa vs 10.5 GPa).
LCP-GF30Choose it when the part sees heat.
LCP Type IIChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
LCP-GF30 vs LCP Type II: 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 II — frequently asked
What is the difference between LCP-GF30 and LCP Type II?
LCP-GF30 and LCP Type II are both polymer grades. LCP Type II is the more ductile: elongation 3.5% versus 2.8% for LCP-GF30. LCP Type II is lighter (1.4 g/cm³ vs 1.61 g/cm³ for LCP-GF30) and LCP-GF30 is stiffer (15 GPa vs 10.5 GPa).
Which is cheaper, LCP-GF30 or LCP Type II?
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.
When should I choose LCP-GF30 over LCP Type II?
Pick LCP-GF30 when the part sees heat. Pick LCP Type II when the part is bent, formed or impact-loaded, or when weight is the constraint.
