LCP Type III vs Sumikasuper
Polymer · grade comparison
LCP Type III and Sumikasuper are both polymer grades. Sumikasuper is the stronger of the two: tensile strength 160 MPa (23.2 ksi) against 150 MPa (21.8 ksi) for LCP Type III, about 7% more. In exchange, LCP Type III is the more ductile: elongation 3% versus 2.2% for Sumikasuper. LCP Type III is lighter (1.4 g/cm³ vs 1.62 g/cm³ for Sumikasuper) and Sumikasuper is stiffer (14 GPa vs 10 GPa). On the shop floor, LCP Type III machines more easily (good vs fair).
LCP Type IIIChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
SumikasuperChoose it when strength drives the design, or when the part sees heat.
LCP Type III vs Sumikasuper: 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 Sumikasuper — frequently asked
Is Sumikasuper stronger than LCP Type III?
Yes. Sumikasuper has a typical tensile strength of 160 MPa (23.2 ksi) against 150 MPa (21.8 ksi) for LCP Type III — about 7% more.
Which is cheaper, LCP Type III or Sumikasuper?
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 III or Sumikasuper?
LCP Type III. Its machinability rates good (55/100) against fair (45/100) for Sumikasuper.
