Tensile strength reaches approximately 58 MPa, flexural modulus sits around 2,300 MPa, and notched Izod impact strength exceeds 5 kJ/m² at 23 °C—respectable numbers for an unfilled resin. The material retains useful impact resistance down to –40 °C and shows good surface hardness together with solid abrasion resistance in light sliding applications.Full detailed guide here →The Benchmark of PBT: A Comprehensive Guide to Duranex 2002
| Property | Typical Value | Unit |
|---|---|---|
| Tensile Strength | ~58 | MPa |
| Flexural Modulus | ~2,300 | MPa |
| Notched Izod Impact (23°C) | > 5.0 | kJ/m² |
| Low-Temp Impact | Retains usefulness | Down to –40 °C |
Molding Behavior & Dimensional Stability
Melt flow rate falls in the 18–25 g/10 min range (250 °C / 2.16 kg), giving smooth flow into thin walls and complex cores without excessive flash or short shots. Mold shrinkage stays between 1.6% and 2.0% and remains highly isotropic. Water absorption after 24 h immersion at 23 °C measures below 0.08%, so molded parts resist swelling, warping, or loss of tolerances in humid conditions or after secondary operations.
