LCP Type II vs Sumikasuper
Polymer · grade comparison
LCP Type II and Sumikasuper are both polymer grades. LCP Type II is the stronger of the two: tensile strength 180 MPa (26.1 ksi) against 160 MPa (23.2 ksi) for Sumikasuper, about 13% more. LCP Type II is the more ductile: elongation 3.5% versus 2.2% for Sumikasuper. LCP Type II is lighter (1.4 g/cm³ vs 1.62 g/cm³ for Sumikasuper) and Sumikasuper is stiffer (14 GPa vs 10.5 GPa). On the shop floor, LCP Type II machines more easily (good vs fair).
LCP Type IIChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
SumikasuperChoose it when the part sees heat.
LCP Type II 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 II vs Sumikasuper — frequently asked
Is LCP Type II stronger than Sumikasuper?
Yes. LCP Type II has a typical tensile strength of 180 MPa (26.1 ksi) against 160 MPa (23.2 ksi) for Sumikasuper — about 13% more.
Which is cheaper, LCP Type II 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 II or Sumikasuper?
LCP Type II. Its machinability rates good (55/100) against fair (45/100) for Sumikasuper; for welding the order is Sumikasuper first (poor, 30/100) then LCP Type II (poor, 25/100).
