PBAT Compound Supplier

PBAT has high melt viscosity and a relatively low melt strength. Therefore, it is recommended to use a single screw extruder to process it. The processing temperature may vary according to the specific PBAT used, but is usually between 170°C and 220°C using a residence time of 3-5 minutes. The melt temperature must be controlled tightly to avoid overheating the material, which can lead to potential thermal degradation.

The introduction of compatibilizers and additives can enhance the properties of PBAT, improving its impact resistance, tensile strength, and thermal stability. These additives can also make the material more eco-friendly by enhancing its biodegradability.
