Questions Is Plastic PMMA stronger than Plastic Polypropylene? Plastic PMMA is stronger: its tensile strength is 80 MPa against yield strength 33 MPa for Plastic Polypropylene (2.42x).
Which is lighter, Plastic PMMA or Plastic Polypropylene? Plastic Polypropylene is lighter: 900 kg/m³ against 1,190 kg/m³ for Plastic PMMA.
Which is stiffer, Plastic PMMA or Plastic Polypropylene? Plastic PMMA is stiffer: Young's modulus 3.3 GPa against 1.45 GPa for Plastic Polypropylene, so the same part in Plastic PMMA deflects less under the same load.
Which is lighter for the same job, Plastic PMMA or Plastic Polypropylene? For the same stiffness or strength: Plastic PMMA is lighter for a stiff rod or tie (tension), stiff beam (bending), strong rod or tie, strong beam, strong panel or plate.
Part that must be Plastic PMMA Plastic Polypropylene Stiff rod or tie (tension) lighter 1.72x heavier Stiff beam (bending) lighter 14% heavier Stiff panel or plate about equal about equal Strong rod or tie lighter 1.83x heavier Strong beam lighter 36% heavier Strong panel or plate lighter 18% 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 Polypropylene? Plastic Polypropylene conducts heat better: 0.195 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 90 µm/m·K for Plastic Polypropylene.
