Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Plastic TPU is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Is Plastic PTFE stronger than Plastic TPU? Plastic TPU is stronger: its tensile strength is 23.7 MPa against yield strength 9 MPa for Plastic PTFE (2.63x).
Which is lighter, Plastic PTFE or Plastic TPU? Plastic TPU is lighter: 1,220 kg/m³ against 2,160 kg/m³ for Plastic PTFE.
Which is lighter for the same job, Plastic PTFE or Plastic TPU? For the same stiffness or strength: Plastic TPU is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be Plastic PTFE Plastic TPU Strong rod or tie 4.66x heavier lighter Strong beam 3.38x heavier lighter Strong panel or plate 2.87x 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).
