PBAT is a semi-crystalline polymer, usually the crystallization temperature is around 110℃, the melting point is around 130℃, and the density is between 1.18g/ml~1.3g/ml. The crystallinity of PBAT is about 30%, and the Shore hardness is above 85. PBAT is a copolymer of aliphatic and aromatic, which combines the excellent degradation performance of aliphatic polyester and the good mechanical properties of aromatic polyester. The processing performance of PBAT is very similar to that of LDPE, and the film can be blown with LDPE processing equipment.
