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 LCP GF30 stronger than Plastic Nylon?
Plastic LCP GF30 is stronger: its tensile strength is 115 MPa against yield strength 63.1 MPa for Plastic Nylon (1.82x).
Which is lighter, Plastic LCP GF30 or Plastic Nylon?
Plastic Nylon is lighter: 1,140 kg/m³ against 1,610 kg/m³ for Plastic LCP GF30.
Which is stiffer, Plastic LCP GF30 or Plastic Nylon?
Plastic LCP GF30 is stiffer: Young's modulus 11.5 GPa against 2.33 GPa for Plastic Nylon, so the same part in Plastic LCP GF30 deflects less under the same load.
Which is lighter for the same job, Plastic LCP GF30 or Plastic Nylon?
For the same stiffness or strength: Plastic LCP GF30 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam; Plastic Nylon is lighter for a strong panel or plate.
| Part that must be | Plastic LCP GF30 | Plastic Nylon |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 3.49x heavier |
| Stiff beam (bending) | lighter | 1.57x heavier |
| Stiff panel or plate | lighter | 21% heavier |
| Strong rod or tie | lighter | 29% heavier |
| Strong beam | lighter | 6% heavier |
| Strong panel or plate | 5% 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 LCP GF30 or Plastic Nylon?
Plastic LCP GF30 conducts heat better: 0.5 W/m·K against 0.33 W/m·K for Plastic Nylon.
Which expands less with temperature?
Plastic LCP GF30 expands less: 20 µm/m·K against 100 µm/m·K for Plastic Nylon.
