Questions Mechanical Is Plastic Nylon PA66 stronger than Plastic PPS GF40? Plastic PPS GF40 is stronger: its tensile strength is 195 MPa against yield strength 85 MPa for Plastic Nylon PA66 (2.29x).
Which is lighter, Plastic Nylon PA66 or Plastic PPS GF40? Plastic Nylon PA66 is lighter: 1,130 kg/m³ against 1,650 kg/m³ for Plastic PPS GF40.
Which is stiffer, Plastic Nylon PA66 or Plastic PPS GF40? Plastic PPS GF40 is stiffer: Young's modulus 14.7 GPa against 3 GPa for Plastic Nylon PA66, so the same part in Plastic PPS GF40 deflects less under the same load.
Which is lighter for the same job, Plastic Nylon PA66 or Plastic PPS GF40? For the same stiffness or strength: Plastic PPS GF40 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 Nylon PA66 Plastic PPS GF40 Stiff rod or tie (tension) 3.36x heavier lighter Stiff beam (bending) 1.52x heavier lighter Stiff panel or plate 16% heavier lighter Strong rod or tie 1.57x heavier lighter Strong beam 19% heavier lighter Strong panel or plate 4% 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 is more ductile, Plastic Nylon PA66 or Plastic PPS GF40? Plastic Nylon PA66 stretches further before it breaks: 30% elongation at break against 1.9% for Plastic PPS GF40.
Thermal Which conducts heat better, Plastic Nylon PA66 or Plastic PPS GF40? Plastic Nylon PA66 conducts heat better: 0.33 W/m·K against 0.2 W/m·K for Plastic PPS GF40.
Which expands less with temperature? Plastic PPS GF40 expands less: 12 µm/m·K against 98 µm/m·K for Plastic Nylon PA66.
