Slow crystallization
WebbPHB. Especially the slow crystallization rate is an obstacle for large-scale applications of PHB. Due to the high rate of post-crystallization, the cycle times in injection molding of PHB cannot be compared to those of conventional plastics or other bioplastics. Nevertheless to use the good properties of PHB, the crystallization has to be ... Webb1 jan. 2024 · The larger these descriptors, the slower the crystallization.
