WebOct 11, 2024 · The high temperature application of polylactide (PLA) has been greatly limited by its low heat deflection temperature (HDT). As a slow crystallizing material, the HDT of amorphous PLA is mainly determined by its low T g value, near 55°C. In this work, PLA was chemically crosslinked, and the HDT of the crosslinked PLA was evaluated … http://polymerdatabase.com/Films/PLA%20Films.html

http://polymerdatabase.com/Films/PLA%20Films.html WebSome novel grades also have much improved heat stability and can withstand temperatures up to 120°C (HDT, 0.45MPa). 2 However, typical grades have a relative low heat deflection temperature in the range of 50 - 60°C. The heat performance of general purpose PLA is typically between LDPE and HDPE and its impact strength is comparable to HIPS ...
WebThe deflection temperature is the temperature at which a test bar, loaded to the specified bending stress, deflects by 0.010 inch (0.25 mm). The value obtained for a specific polymer grade will depend on the base resin and on the presence of reinforcing agents. Deflection temperatures of glass fiber or carbon fiber reinforced engineering ... WebThe experience is that the temperatures for heat deflection temperature (HDT-A), the heat resistance temperature of PLA, are ∼15–25 °C lower than those for Vicat (B50) melting …
