Questions Is Plastic HDPE stronger than Plastic LCP GF30? Plastic LCP GF30 is stronger: its tensile strength is 115 MPa against yield strength 24 MPa for Plastic HDPE (4.79x).
Which is lighter, Plastic HDPE or Plastic LCP GF30? Plastic HDPE is lighter: 950 kg/m³ against 1,610 kg/m³ for Plastic LCP GF30.
Which is stiffer, Plastic HDPE or Plastic LCP GF30? Plastic LCP GF30 is stiffer: Young's modulus 11.5 GPa against 0.9 GPa for Plastic HDPE, so the same part in Plastic LCP GF30 deflects less under the same load.
Which is lighter for the same job, Plastic HDPE or Plastic LCP GF30? 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.
Part that must be Plastic HDPE Plastic LCP GF30 Stiff rod or tie (tension) 7.54x heavier lighter Stiff beam (bending) 2.11x heavier lighter Stiff panel or plate 38% heavier lighter Strong rod or tie 2.83x heavier lighter Strong beam 1.68x heavier lighter Strong panel or plate 29% 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 HDPE or Plastic LCP GF30? Plastic LCP GF30 conducts heat better: 0.5 W/m·K against 0.445 W/m·K for Plastic HDPE.
Which expands less with temperature? Plastic LCP GF30 expands less: 20 µm/m·K against 120 µm/m·K for Plastic HDPE.
