1.At present, the global biodegradable plastics market is dominated by PLA and PBAT. From the performance point of view, PLA has good heat resistance, stable performance at room temperature, good gloss, but poor toughness, and general gas barrier properties; PBAT has good mechanical properties, good toughness, and high thermal stability. But the intensity is low.
2.The degradable plastic products used on a large scale on the market have been modified or compounded. Among them, PBAT is mainly used in combination with PLA. The respective proportions of PBAT and PLA should be determined according to the use of the final product. In other words, PLA and PBAT have a strong correlation.
