What is PBAT? Uses and Step-by-Step Manufacturing Process
PBAT Polymer is a fully biodegradable aliphatic-aromatic copolyester. It combines the softness and flexibility of aliphatic polyesters with the mechanical strength of aromatic polyesters. This unique combination allows PBAT to provide high elongation at break, excellent tear resistance, and easy processability. PBAT can be blended with other biodegradable polymers such as PLA (Polylactic Acid) to enhance mechanical properties and produce high-performance compostable products.
Uses of PBAT
- Compostable Bags: For biodegradable shopping bags, waste bags, and food packaging.
- Flexible Packaging: Suitable for agricultural films, stretch wraps, and laminated materials.
- Blended Bioplastics: Combined with PLA or starch to enhance flexibility and tear resistance.
- Eco-Friendly Products: Used in disposable tableware, cutlery, and single-use items to reduce plastic pollution.
Step-by-Step PBAT Manufacturing Process
- Raw Material Preparation: Purified monomers (adipic acid, 1,4-butanediol, terephthalic acid) are prepared to ensure polymer quality.
- Esterification: Adipic acid and 1,4-butanediol form a prepolymer, releasing water under controlled conditions.
- Polycondensation: Prepolymer reacts with terephthalic acid to build the long-chain PBAT structure.
- Vacuum Drying and Degassing: Residual water and volatiles are removed for thermal stability and processability.
- Extrusion: Molten PBAT is extruded into pellets for film or product manufacturing.
- Cooling and Packaging: Pellets are cooled, dried, and packaged, ready for shipment to manufacturers.
