Questions Is Plastic POM/Acetal stronger than Plywood? Plastic POM/Acetal is stronger: its yield strength is 69 MPa against tensile strength 41.4 MPa for Plywood (1.67x).
Which is stiffer, Plastic POM/Acetal or Plywood? Plywood is stiffer: Young's modulus 7.45 GPa against 2.8 GPa for Plastic POM/Acetal, so the same part in Plywood deflects less under the same load.
Which conducts heat better, Plastic POM/Acetal or Plywood? Plastic POM/Acetal 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 122 µm/m·K for Plastic POM/Acetal.
