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 Plywood stronger than Plastic PMMA? Plastic PMMA is stronger: its tensile strength is 80 MPa against 41.4 MPa for Plywood (1.93x).
Which is stiffer, Plywood or Plastic PMMA? Plywood is stiffer: Young's modulus 7.45 GPa against 3.3 GPa for Plastic PMMA, so the same part in Plywood deflects less under the same load.
Which conducts heat better, Plywood or Plastic PMMA? Plastic PMMA conducts heat better: 0.19 W/m·K against 0.12 W/m·K for Plywood.
Which expands less with temperature? Plywood expands less: 3.8 µm/m·K against 70 µm/m·K for Plastic PMMA.
