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.
Questions Is Plastic PMMA stronger than Plastic PTFE? Plastic PMMA is stronger: its tensile strength is 80 MPa against yield strength 9 MPa for Plastic PTFE (8.89x).
Which is lighter, Plastic PMMA or Plastic PTFE? Plastic PMMA is lighter: 1,190 kg/m³ against 2,160 kg/m³ for Plastic PTFE.
Which is lighter for the same job, Plastic PMMA or Plastic PTFE? For the same stiffness or strength: Plastic PMMA is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be Plastic PMMA Plastic PTFE Strong rod or tie lighter 16.1x heavier Strong beam lighter 7.79x heavier Strong panel or plate lighter 5.41x 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 conducts heat better, Plastic PMMA or Plastic PTFE? Plastic PTFE conducts heat better: 0.25 W/m·K against 0.19 W/m·K for Plastic PMMA.
Which expands less with temperature? Plastic PMMA expands less: 70 µm/m·K against 100 µm/m·K for Plastic PTFE.
