Questions

Is Drywall stronger than Plastic Polycarbonate?

Plastic Polycarbonate is stronger: its yield strength is 65 MPa against tensile strength 1.5 MPa for Drywall (43.3x).

Which is stiffer, Drywall or Plastic Polycarbonate?

Plastic Polycarbonate is stiffer: Young's modulus 2.4 GPa against 1.5 GPa for Drywall, so the same part in Plastic Polycarbonate deflects less under the same load.

Which expands less with temperature?

Drywall expands less: 16.7 µm/m·K against 65 µm/m·K for Plastic Polycarbonate.
