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 PEEK stronger than Plywood? Plastic PEEK is stronger: its yield strength is 98 MPa against tensile strength 41.4 MPa for Plywood (2.37x).
Which is stiffer, Plastic PEEK or Plywood? Plywood is stiffer: Young's modulus 7.45 GPa against 4 GPa for Plastic PEEK, so the same part in Plywood deflects less under the same load.
Which conducts heat better, Plastic PEEK or Plywood? Plastic PEEK conducts heat better: 0.29 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 55 µm/m·K for Plastic PEEK.
