Questions
Is Plastic PPS GF40 stronger than Solder SAC305?
Plastic PPS GF40 is stronger: its tensile strength is 195 MPa against yield strength 22 MPa for Solder SAC305 (8.86x).
Which is lighter, Plastic PPS GF40 or Solder SAC305?
Plastic PPS GF40 is lighter: 1,650 kg/m³ against 7,350 kg/m³ for Solder SAC305.
Which is stiffer, Plastic PPS GF40 or Solder SAC305?
Plastic PPS GF40 is stiffer: Young's modulus 14.7 GPa against 6.9 GPa for Solder SAC305, so the same part in Plastic PPS GF40 deflects less under the same load.
Which is lighter for the same job, Plastic PPS GF40 or Solder SAC305?
For the same stiffness or strength: Plastic PPS GF40 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be
Plastic PPS GF40
Solder SAC305
Stiff rod or tie (tension)
lighter
9.49x heavier
Stiff beam (bending)
lighter
6.5x heavier
Stiff panel or plate
lighter
5.73x heavier
Strong rod or tie
lighter
39.5x heavier
Strong beam

19.1x heavier
Strong panel or plate
lighter
13.3x heavier
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 conducts heat better, Plastic PPS GF40 or Solder SAC305?
Solder SAC305 conducts heat better: 61 W/m·K against 0.2 W/m·K for Plastic PPS GF40.
Which expands less with temperature?
Plastic PPS GF40 expands less: 12 µm/m·K against 21.9 µm/m·K for Solder SAC305.
