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 UHMWPE? Plywood is stronger: its tensile strength is 41.4 MPa against yield strength 20 MPa for Plastic UHMWPE (2.07x).
Which is stiffer, Plywood or Plastic UHMWPE? Plywood is stiffer: Young's modulus 7.45 GPa against 0.66 GPa for Plastic UHMWPE, so the same part in Plywood deflects less under the same load.
Which conducts heat better, Plywood or Plastic UHMWPE? Plastic UHMWPE conducts heat better: 0.4 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 200 µm/m·K for Plastic UHMWPE.
