Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions Mechanical Is Plastic ABS (bulk/injection) stronger than Plastic Nylon PA6? Plastic Nylon PA6 is stronger: its yield strength is 90 MPa against 45 MPa for Plastic ABS (bulk/injection) (2x).
Which is lighter, Plastic ABS (bulk/injection) or Plastic Nylon PA6? Plastic ABS (bulk/injection) is lighter: 1,040 kg/m³ against 1,130 kg/m³ for Plastic Nylon PA6.
Which is stiffer, Plastic ABS (bulk/injection) or Plastic Nylon PA6? Plastic Nylon PA6 is stiffer: Young's modulus 3.5 GPa against 2.3 GPa for Plastic ABS (bulk/injection), so the same part in Plastic Nylon PA6 deflects less under the same load.
Which is lighter for the same job, Plastic ABS (bulk/injection) or Plastic Nylon PA6? For the same stiffness or strength: Plastic Nylon PA6 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be Plastic ABS (bulk/injection) Plastic Nylon PA6 Stiff rod or tie (tension) 40% heavier lighter Stiff beam (bending) 14% heavier lighter Stiff panel or plate 6% heavier lighter Strong rod or tie 1.84x heavier lighter Strong beam 46% heavier lighter Strong panel or plate 30% heavier lighter
For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
Thermal Which conducts heat better, Plastic ABS (bulk/injection) or Plastic Nylon PA6? Plastic Nylon PA6 conducts heat better: 0.33 W/m·K against 0.17 W/m·K for Plastic ABS (bulk/injection).
Which expands less with temperature? Plastic ABS (bulk/injection) expands less: 95 µm/m·K against 102 µm/m·K for Plastic Nylon PA6.
