PA11 EOS PA 1101 vs PA11 Sinterit PA11 CF

Polymer · PA11 grade comparison

EOS PA 1101 and Sinterit PA11 CF are two grades of the same polymer grade, PA11: EOS PA 1101 versus Sinterit PA11 CF. 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 50 MPa (7.25 ksi) for EOS PA 1101, about 62% more. In exchange, EOS PA 1101 is the more ductile: elongation 30% versus 24.5% for Sinterit PA11 CF, and Sinterit PA11 CF is harder (81 Shore D vs 75 Shore D). EOS PA 1101 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 1.65 GPa).

EOS PA 1101Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

Sinterit PA11 CFChoose it when strength drives the design.
