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.
Plastic Nylon is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Mechanical Is Plastic Nylon stronger than Plastic Nylon PA66? Plastic Nylon PA66 is stronger: its yield strength is 85 MPa against 63.1 MPa for Plastic Nylon (35%).
Which is lighter, Plastic Nylon or Plastic Nylon PA66? Plastic Nylon PA66 is lighter: 1,130 kg/m³ against 1,140 kg/m³ for Plastic Nylon.
Which is stiffer, Plastic Nylon or Plastic Nylon PA66? Plastic Nylon PA66 is stiffer: Young's modulus 3 GPa against 2.33 GPa for Plastic Nylon, so the same part in Plastic Nylon PA66 deflects less under the same load.
Which is lighter for the same job, Plastic Nylon or Plastic Nylon PA66? For the same stiffness or strength: Plastic Nylon PA66 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 Nylon Plastic Nylon PA66 Stiff rod or tie (tension) 30% heavier lighter Stiff beam (bending) 14% heavier lighter Stiff panel or plate 10% heavier lighter Strong rod or tie 36% heavier lighter Strong beam 23% heavier lighter Strong panel or plate 17% 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 Nylon or Plastic Nylon PA66? Plastic Nylon conducts heat better: 0.33 W/m·K against 0.33 W/m·K for Plastic Nylon PA66.
Which expands less with temperature? Plastic Nylon PA66 expands less: 98 µm/m·K against 100 µm/m·K for Plastic Nylon.
