Laperos vs LCP Type II
Polymer · grade comparison
Laperos and LCP Type II are both polymer grades. LCP Type II is the stronger of the two: tensile strength 180 MPa (26.1 ksi) against 165 MPa (23.9 ksi) for Laperos, about 9% more. LCP Type II is the more ductile: elongation 3.5% versus 2.5% for Laperos. LCP Type II is lighter (1.4 g/cm³ vs 1.61 g/cm³ for Laperos) and Laperos is stiffer (14 GPa vs 10.5 GPa). On the shop floor, LCP Type II machines more easily (good vs fair).
LaperosChoose it when the part sees heat.
LCP Type IIChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Laperos 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.

Laperos vs LCP Type II — frequently asked
Is LCP Type II stronger than Laperos?
Yes. LCP Type II has a typical tensile strength of 180 MPa (26.1 ksi) against 165 MPa (23.9 ksi) for Laperos — about 9% more.
Which is cheaper, Laperos 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.
Which is easier to machine, Laperos or LCP Type II?
LCP Type II. Its machinability rates good (55/100) against fair (40/100) for Laperos.
