Questions
Is Plastic LCP GF30 stronger than Plastic Polypropylene?
Plastic LCP GF30 is stronger: its tensile strength is 115 MPa against yield strength 33 MPa for Plastic Polypropylene (3.48x).
Which is lighter, Plastic LCP GF30 or Plastic Polypropylene?
Plastic Polypropylene is lighter: 900 kg/m³ against 1,610 kg/m³ for Plastic LCP GF30.
Which is stiffer, Plastic LCP GF30 or Plastic Polypropylene?
Plastic LCP GF30 is stiffer: Young's modulus 11.5 GPa against 1.45 GPa for Plastic Polypropylene, 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 Polypropylene?
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, 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 conducts heat better, Plastic LCP GF30 or Plastic Polypropylene?
Plastic LCP GF30 conducts heat better: 0.5 W/m·K against 0.195 W/m·K for Plastic Polypropylene.
Which expands less with temperature?
Plastic LCP GF30 expands less: 20 µm/m·K against 90 µm/m·K for Plastic Polypropylene.
