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 Drywall stronger than Plastic PEEK? Plastic PEEK is stronger: its yield strength is 98 MPa against tensile strength 1.5 MPa for Drywall (65.3x).
Which is stiffer, Drywall or Plastic PEEK? Plastic PEEK is stiffer: Young's modulus 4 GPa against 1.5 GPa for Drywall, so the same part in Plastic PEEK deflects less under the same load.
Which expands less with temperature? Drywall expands less: 16.7 µm/m·K against 55 µm/m·K for Plastic PEEK.
