Sumikasuper vs Zenite
Polymer · grade comparison
Sumikasuper and Zenite are both polymer grades. Zenite is the more ductile: elongation 3.5% versus 2.2% for Sumikasuper. Zenite is lighter (1.4 g/cm³ vs 1.62 g/cm³ for Sumikasuper) and Sumikasuper is stiffer (14 GPa vs 11 GPa). On the shop floor, Zenite machines more easily (good vs fair).

Sumikasuper vs Zenite: 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.

Sumikasuper vs Zenite — frequently asked
What is the difference between Sumikasuper and Zenite?
Sumikasuper and Zenite are both polymer grades. Zenite is the more ductile: elongation 3.5% versus 2.2% for Sumikasuper. Zenite is lighter (1.4 g/cm³ vs 1.62 g/cm³ for Sumikasuper) and Sumikasuper is stiffer (14 GPa vs 11 GPa).
Which is cheaper, Sumikasuper or Zenite?
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, Sumikasuper or Zenite?
Zenite. Its machinability rates good (55/100) against fair (45/100) for Sumikasuper.
