PBAT (Polybutylene Adipate Terephthalate) is a type of thermoplastic polymer that is quickly gaining popularity as an eco-friendly alternative to traditional petroleum-based plastics.
PBAT is made from renewable resources such as sugar cane and corn starch and is a copolymer of polybutylene adipate and terephthalic acid.
PBAT polymer can be processed using conventional plastic processing techniques and can be blended with other biodegradable polymers to improve its properties.

Advantages
Good Ductility: PBAT (polybutylene adipate terephthalate) is a type of biodegradable plastic known for its good ductility, which refers to a material's ability to deform under stress without breaking. PBAT has a relatively high elongation at break, which means it can stretch without breaking. For example, PBAT films can stretch up to 350% of their original length before breaking, and this property makes PBAT plastic ideal for flexible packaging applications, including food packaging or compostable bags.
Good Elongation at Break: PBAT has an excellent elongation at break, which means that it can stretch considerably before breaking. The elongation at break for PBAT can range from 100% to 700%. For instance, PBAT fibers may have an elongation at a break of around 200%, and this property makes PBAT plastic suitable for applications requiring high flexibility and stretchability, such as disposable gloves or stretch wrap.
Good Heat Resistance: PBAT has good heat resistance, meaning that it can withstand high temperatures without degrading or losing its physical properties.
The melting temperature of PBAT is around 160-170°C, and its glass transition temperature is around -30°C, which makes PBAT plastic suitable for applications requiring high-temperature resistance, like microwaveable food containers or hot drink cups.
Excellent Biodegradability: One of the most significant benefits of PBAT plastic is its excellent biodegradability – PBAT is a biodegradable polyester that can decompose under aerobic and anaerobic conditions. The biodegradation rate of PBAT can vary depending on the environmental conditions, but it typically takes 60 to 120 days for PBAT to biodegrade in soil or compost completely. Meanwhile, this property helps PBAT plastic to become an ideal choice for applications that require sustainable and eco-friendly materials, incorporating single-use packaging or disposable cutlery.
PBAT materials are suitable for various types of equipment, such as small film blowing machines, extruders, internal mixers, two-roller mixers, cast film equipment and other experimental equipment.
