Laperos vs LCP Type I
Polymer · grade comparison
Laperos and LCP Type I are both polymer grades. Laperos is the stronger of the two: tensile strength 165 MPa (23.9 ksi) against 135 MPa (19.6 ksi) for LCP Type I, about 22% more. LCP Type I is lighter (1.38 g/cm³ vs 1.61 g/cm³ for Laperos) and Laperos is stiffer (14 GPa vs 11 GPa). On the shop floor, LCP Type I machines more easily (good vs fair).
LaperosChoose it when strength drives the design.
LCP Type IChoose it when weight is the constraint, or when the part is machined in volume.
Laperos 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.

Laperos vs LCP Type I — frequently asked
Is Laperos stronger than LCP Type I?
Yes. Laperos has a typical tensile strength of 165 MPa (23.9 ksi) against 135 MPa (19.6 ksi) for LCP Type I — about 22% more.
Which is cheaper, Laperos 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, Laperos or LCP Type I?
LCP Type I. Its machinability rates good (62/100) against fair (40/100) for Laperos; for welding the order is Laperos first (poor, 25/100) then LCP Type I (poor, 20/100).
