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