WebMar 30, 2024 · The heat distortion temperature (HDT) of PP-1 was 76 °C due to its high stiffness. Although the flexural modulus of PP-3 (914 MPa) was much higher than PP-2 (739 MPa), the HDT of PP-3 (62 °C) was lower than that of PP-2 (69 °C), which may be attributed to their different rubber phase sizes. WebIn polypropylene formulations, adding nucleating agents (also called nucleators) result in improved performance & processing properties, such as: Improved clarity and reduced haze. Improved strength and stiffness. Improved Heat Deflection Temperature (HDT) Reduced cycle time. Reduced warpage and more uniform shrinkage.
