Melt processing of biodegradable poly(butylene succinate) (PBS)—a critical review

This review paper presents a comprehensive analysis of the melt processing of polybutylene succinate (PBS) blends and composites. PBS, a biodegradable and eco-friendly thermoplastic polyester, has garnered significant interest in sustainable material research. The paper collates and examines a wide range of studies focusing on the processability, optimization of processing parameters, and resultant mechanical properties of PBS when processed through several extrusion techniques and by injection molding. Key parameters such as melt temperature, screw speed, and mold temperature are considered for their impact on the quality and performance of the final product. The review highlights advancements in processing technologies and material modifications that enhance PBS properties, making it a viable alternative to traditional petroleum-based plastics. Furthermore, challenges and limitations in the current processing techniques are discussed, offering insights into potential areas for future research. The synthesis of findings from various studies provides a holistic understanding of the state-of-the-art in PBS processing, aiming to guide further developments in the field of biodegradable polymers. Overall, this review underscores the importance of optimized melt processing techniques in maximizing the potential of PBS as a sustainable material in diverse applications.
