Polymer thermal expansion coefficient

WebBepex works with PLA producers to extend the uses for PLA polymers through post-processing thermal treatment. Bepex equipment provides the precise control needed to crystallize the plastic pellets, making them easier to process, stronger, and less transparent. That makes them usable in more products, expanding markets for this sustainable solution. WebDec 6, 2024 · The high density and packing coefficient of the resulting PIs caused by the strong intermolecular interaction from the hydrogen bonds and the charge-transfer complex provided the PI films with a very high glass-transition temperature (T g > 450 °C) and an extremely low coefficient of thermal expansion (CTE) below 10 ppm/K for PI-a.
