Poly(1,4-butylene adipate) is widely used in the production of biodegradable plastics and polymers. It is a key component in creating environmentally friendly materials, such as compostable packaging, agricultural films, and disposable items. Its ability to break down naturally makes it suitable for applications where reducing plastic waste is critical. Additionally, it is utilized in the manufacturing of adhesives, coatings, and elastomers, providing flexibility and durability. In the biomedical field, it is employed for controlled drug delivery systems and tissue engineering scaffolds due to its biocompatibility and degradation properties. It is also used in synthetic fibers and yarns for the textile industry. Its versatility and eco-friendly nature make it a valuable material in sustainable industrial and medical applications.
