Questions

Is Plastic ABS (bulk/injection) stronger than Plastic LCP GF30?

Plastic LCP GF30 is stronger: its tensile strength is 115 MPa against yield strength 45 MPa for Plastic ABS (bulk/injection) (2.56x).

Which is lighter, Plastic ABS (bulk/injection) or Plastic LCP GF30?

Plastic ABS (bulk/injection) is lighter: 1,040 kg/m³ against 1,610 kg/m³ for Plastic LCP GF30.

Which is stiffer, Plastic ABS (bulk/injection) or Plastic LCP GF30?

Plastic LCP GF30 is stiffer: Young's modulus 11.5 GPa against 2.3 GPa for Plastic ABS (bulk/injection), so the same part in Plastic LCP GF30 deflects less under the same load.

Which is lighter for the same job, Plastic ABS (bulk/injection) 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 bePlastic ABS (bulk/injection)Plastic LCP GF30
Stiff rod or tie (tension)3.23x heavierlighter
Stiff beam (bending)44% heavierlighter
Stiff panel or plate10% heavierlighter
Strong rod or tie1.65x heavierlighter
Strong beam21% heavierlighter
Strong panel or plate3% heavierlighter

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 ABS (bulk/injection) or Plastic LCP GF30?

Plastic LCP GF30 conducts heat better: 0.5 W/m·K against 0.17 W/m·K for Plastic ABS (bulk/injection).

Which expands less with temperature?

Plastic LCP GF30 expands less: 20 µm/m·K against 95 µm/m·K for Plastic ABS (bulk/injection).
