PBAT Granule

Products Description

PBAT is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of both PBA and PBT, with good ductility and elongation at break, as well as good heat resistance and impact performance; in addition, it also has excellent biodegradability, and is one of the most popular and best degradable materials in biodegradable plastic research and market application.

 

PBAT is a semi-crystalline polymer, usually with a crystallization temperature around 110°C and a melting point around 130°C. The density of PBAT is between 1.18g/ml and 1.3g/ml. The crystallinity of PBAT is around 30% and the Shore hardness is above 85. PBAT is a copolymer of aliphatic and aromatic, combining 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 and can be blown with LDPE processing equipment.

 

 

The plastic packaging industry generates a large amount of plastic waste, much of which ends up in landfills. By moving to compostable packaging solutions, the industry can significantly reduce plastic pollution. PBAT is mainly used in the plastic packaging industry, such as shopping bags and garbage bags, but also in tableware and mulch.
