LCP Type I vs Xydar
Polymer · grade comparison
LCP Type I and Xydar are both polymer grades. Xydar is stiffer (12 GPa vs 11 GPa) and Xydar runs hotter in service (240°C vs 220°C continuous).

LCP Type I vs Xydar: 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 Type I vs Xydar — frequently asked
What is the difference between LCP Type I and Xydar?
LCP Type I and Xydar are both polymer grades. Xydar is stiffer (12 GPa vs 11 GPa) and Xydar runs hotter in service (240°C vs 220°C continuous).
Which is cheaper, LCP Type I or Xydar?
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 Type I or Xydar?
LCP Type I, by a small margin. Both rate good for machinability — 62/100 against 55/100 for Xydar; for welding the order is Xydar first (poor, 25/100) then LCP Type I (poor, 20/100).
