Polybutylene Adipate Terephthalate
Polybutylene adipate terephthalate (PBAT) is a type of biodegradable and bio-based thermoplastic polymer. It is a copolyester made from the monomers 1,4-butanediol, terephthalic acid, and adipic acid. PBAT is often used as a component in biodegradable and compostable products, such as disposable tableware, shopping bags, and packaging materials. It can also be used as a component in other products, such as coatings and adhesives.

Polybutylene Adipate Terephthalate (PBAT) is a biodegradable and compostable thermoplastic polymer. It is a copolymer of polybutylene adipate (PBA) and polyethylene terephthalate (PET).

The main properties of PBAT include:
1. Biodegradability: One of the most significant benefits of PBAT is its biodegradability. When exposed to certain environmental conditions (e.g., composting facilities or soil), PBAT breaks down into natural byproducts such as carbon dioxide, water and biomass through the action of microorganisms. This biodegradability helps reduce the accumulation of plastic waste in landfills and the environment, contributing to a more sustainable future.

2. Versatility: PBAT is a highly versatile polymer that can be processed using a variety of traditional plastics manufacturing techniques, including extrusion, injection molding and blown film extrusion. Its compatibility with existing machinery and processes makes it a practical choice for transitioning from traditional plastics to more sustainable options. PBAT is often blended with other biopolymers to improve its toughness and impact strength.

3. Mechanical properties: PBAT has good mechanical strength, flexibility and elongation at break. It can be used to produce films, sheets and molded products with properties comparable to those of conventional polyethylene and polypropylene.

4. Heat resistance: While PBAT may not have the same heat resistance as some convent
