PBAT is thermoplastic biodegradable plastics. It is a copolymer of butanediol adipate and butanediol terephthalate. It has the characteristics of PBA and PBT. It has not only good ductility and elongation at break, but also good heat resistance and impact properties; In addition, it also has excellent biodegradability. It is one of the most active biodegradable materials in the research of biodegradable plastics and one of the best degradable materials in the market.
PBAT is a semi crystalline polymer. The crystallization temperature is usually 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 more than 85. PBAT is a copolymer of aliphatic and aromatic polyesters, which combines the excellent degradation properties of aliphatic polyesters and the good mechanical properties of aromatic polyesters. The processing performance of PBAT is very similar to that of LDPE. LDPE processing equipment can be used for film blowing.
