Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions
Mechanical
Is Copper C10100 stronger than Plastic UHMWPE?
Copper C10100 is stronger: its yield strength is 69 MPa against 20 MPa for Plastic UHMWPE (3.45x).
Which is lighter, Copper C10100 or Plastic UHMWPE?
Plastic UHMWPE is lighter: 930 kg/m³ against 8,941 kg/m³ for Copper C10100.
Which is stiffer, Copper C10100 or Plastic UHMWPE?
Copper C10100 is stiffer: Young's modulus 117 GPa against 0.66 GPa for Plastic UHMWPE, so the same part in Copper C10100 deflects less under the same load.
Which is lighter for the same job, Copper C10100 or Plastic UHMWPE?
For the same stiffness or strength: Copper C10100 is lighter for a stiff rod or tie (tension), stiff beam (bending); Plastic UHMWPE is lighter for a stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.

For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
Which is more ductile, Copper C10100 or Plastic UHMWPE?
Plastic UHMWPE stretches further before it breaks: 465% elongation at break against 45% for Copper C10100.
Thermal
Which conducts heat better, Copper C10100 or Plastic UHMWPE?
Copper C10100 conducts heat better: 391 W/m·K against 0.4 W/m·K for Plastic UHMWPE.
Which expands less with temperature?
Copper C10100 expands less: 16.9 µm/m·K against 200 µm/m·K for Plastic UHMWPE.
