PA11 Sinterit PA11 CF vs PA11 Sinterit PA11 Onyx
Polymer · PA11 grade comparison
Sinterit PA11 CF and Sinterit PA11 Onyx are two grades of the same polymer grade, PA11: Sinterit PA11 CF versus Sinterit PA11 Onyx. The chemistry is identical, so every difference below comes from the condition. Sinterit PA11 CF is the stronger of the two: tensile strength 81 MPa (11.7 ksi) against 55 MPa (7.98 ksi) for Sinterit PA11 Onyx, about 47% more. In exchange, Sinterit PA11 Onyx is the more ductile: elongation 31.6% versus 24.5% for Sinterit PA11 CF, and Sinterit PA11 CF is harder (81 Shore D vs 76 Shore D). Sinterit PA11 Onyx is lighter (1.03 g/cm³ vs 1.09 g/cm³ for Sinterit PA11 CF) and Sinterit PA11 CF is stiffer (2.95 GPa vs 1.68 GPa).
Sinterit PA11 CFChoose it when strength drives the design.
Sinterit PA11 OnyxChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Sinterit PA11 CF vs Sinterit PA11 Onyx: 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.
