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 Nylon PA6 stronger than Plastic POM/Acetal? Plastic Nylon PA6 is stronger: its yield strength is 90 MPa against 69 MPa for Plastic POM/Acetal (30%).
Which is lighter, Plastic Nylon PA6 or Plastic POM/Acetal? Plastic Nylon PA6 is lighter: 1,130 kg/m³ against 1,420 kg/m³ for Plastic POM/Acetal.
Which is stiffer, Plastic Nylon PA6 or Plastic POM/Acetal? Plastic Nylon PA6 is stiffer: Young's modulus 3.5 GPa against 2.8 GPa for Plastic POM/Acetal, so the same part in Plastic Nylon PA6 deflects less under the same load.
Which is lighter for the same job, Plastic Nylon PA6 or Plastic POM/Acetal? 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 Nylon PA6 Plastic POM/Acetal Stiff rod or tie (tension) lighter 1.57x heavier Stiff beam (bending) lighter 40% heavier Stiff panel or plate lighter 35% heavier Strong rod or tie lighter 1.64x heavier Strong beam lighter 1.5x heavier Strong panel or plate lighter 44% heavier
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).
Which is more ductile, Plastic Nylon PA6 or Plastic POM/Acetal? Plastic POM/Acetal stretches further before it breaks: 75% elongation at break against 10% for Plastic Nylon PA6.
Thermal Which conducts heat better, Plastic Nylon PA6 or Plastic POM/Acetal? Plastic POM/Acetal conducts heat better: 0.4 W/m·K against 0.33 W/m·K for Plastic Nylon PA6.
Which expands less with temperature? Plastic Nylon PA6 expands less: 102 µm/m·K against 122 µm/m·K for Plastic POM/Acetal.
