LCP Type III vs Vectra
Polymer · grade comparison
LCP Type III and Vectra are both polymer grades. Vectra is the stronger of the two: tensile strength 182 MPa (26.4 ksi) against 150 MPa (21.8 ksi) for LCP Type III, about 21% more. Vectra is the more ductile: elongation 3.4% versus 3% for LCP Type III. Vectra is stiffer (10.6 GPa vs 10 GPa) and Vectra runs hotter in service (200°C vs 170°C continuous).
VectraChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
LCP Type III vs Vectra: 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 III vs Vectra — frequently asked
Is Vectra stronger than LCP Type III?
Yes. Vectra has a typical tensile strength of 182 MPa (26.4 ksi) against 150 MPa (21.8 ksi) for LCP Type III — about 21% more.
Which is cheaper, LCP Type III or Vectra?
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 welds better, LCP Type III or Vectra?
LCP Type III. Its weldability rates poor (30/100) against poor (25/100) for Vectra.
