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.
Plastic Nylon is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic Nylon stronger than Plastic PPS GF40?
Plastic PPS GF40 is stronger: its tensile strength is 195 MPa against yield strength 63.1 MPa for Plastic Nylon (3.09x).
Which is lighter, Plastic Nylon or Plastic PPS GF40?
Plastic Nylon is lighter: 1,140 kg/m³ against 1,650 kg/m³ for Plastic PPS GF40.
Which is stiffer, Plastic Nylon or Plastic PPS GF40?
Plastic PPS GF40 is stiffer: Young's modulus 14.7 GPa against 2.33 GPa for Plastic Nylon, so the same part in Plastic PPS GF40 deflects less under the same load.
Which is lighter for the same job, Plastic Nylon or Plastic PPS GF40?
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 Nylon | Plastic PPS GF40 |
|---|---|---|
| Stiff rod or tie (tension) | 4.36x heavier | lighter |
| Stiff beam (bending) | 1.74x heavier | lighter |
| Stiff panel or plate | 28% heavier | lighter |
| Strong rod or tie | 2.14x heavier | lighter |
| Strong beam | 47% heavier | lighter |
| Strong panel or plate | 21% heavier | lighter |
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 Nylon or Plastic PPS GF40?
Plastic Nylon conducts heat better: 0.33 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 100 µm/m·K for Plastic Nylon.
