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 Polypropylene stronger than Plywood? Plywood is stronger: its tensile strength is 41.4 MPa against yield strength 33 MPa for Plastic Polypropylene (25%).
Which is stiffer, Plastic Polypropylene or Plywood? Plywood is stiffer: Young's modulus 7.45 GPa against 1.45 GPa for Plastic Polypropylene, so the same part in Plywood deflects less under the same load.
Which conducts heat better, Plastic Polypropylene or Plywood? Plastic Polypropylene conducts heat better: 0.195 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 90 µm/m·K for Plastic Polypropylene.
