Customized Logo: Accepted Uses: household trash, restaurant trash, convenience stores, etc. Characteristics of PBAT PBAT belongs to semi-crystalline polymers, generally its crystallization temperature is around 110°C, melting point is around 130°C, and 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 groups, combining the excellent degradation properties of aliphatic PBAT molecular chain polyesters and the good mechanical properties of aromatic polyesters. The processing properties of PBAT are very similar to those of LDPE, and LDPE processing equipment can be used for blown film.
