Poly Butylene Adipate-Co-Terephthalate (PBAT)


Poly Butylene Adipate-Co-Terephthalate Description:

Poly Butylene Adipate-Co-Terephthalate is a thermoplastic biodegradable plastic. PBAT is a copolymer of butylene adipate and butylene terephthalate. PBAT has both the characteristics of PBA and PBT. PBAT has both good ductility and elongation at break, as well as Good heat resistance and impact performance; in addition, PBAT also has excellent biodegradability, which is very active in the research of biodegradable plastics and one of the best degradable materials for market applications.

PBAT Instruction:

The properties of PBAT can be adjusted by changing the ratio of its monomer units and by combining PBAT with other biodegradable polymers. They are typically similar to high-density or low-density polyethylene and can therefore be used for similar applications in food packaging and agricultural films. In addition, PBAT is fully biodegradable (compostable) and can be processed on conventional blown film equipment used for polyethylene. PBAT has also been investigated as a toughening agent for PLA.

PBAT, also known as polybutylene terephthalate, is a semi-aromatic, biodegradable thermoplastic copolyester that can be easily molded and thermoformed. PBAT is a random copolymerization of 1,4-butanediol, adipic acid, and dimethyl terephthalate (DMT) monomers.

Polybutylene terephthalate (PBAT) is a biodegradable plastic that is the most suitable alternative to traditional plastic bags, agricultural films and disposable utensils.PBAT has a very short degradation cycle, good heat resistance, impact resistance, ductility and elongation at break.PBAT can be processed in a similar way to traditional LDPE.

PBAT Advantages:

1. Good tensile strength, close to that of conventional LDPE.
2. Heat resistance, impact resistance.
3. Good biodegradability, degraded to H2O and Co2 by microorganisms on land or in water, zero harmful substances in soil and water, completely non-toxic.
4. Soft and smooth touch.
