Questions Is Plastic LCP GF30 stronger than Plastic PTFE? Plastic LCP GF30 is stronger: its tensile strength is 115 MPa against yield strength 9 MPa for Plastic PTFE (12.8x).
Which is lighter, Plastic LCP GF30 or Plastic PTFE? Plastic LCP GF30 is lighter: 1,610 kg/m³ against 2,160 kg/m³ for Plastic PTFE.
Which is lighter for the same job, Plastic LCP GF30 or Plastic PTFE? For the same stiffness or strength: Plastic LCP GF30 is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be Plastic LCP GF30 Plastic PTFE Strong rod or tie lighter 17.1x heavier Strong beam lighter 7.33x heavier Strong panel or plate lighter 4.8x 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).
