Used primarily in the production of biodegradable polymers, this chemical is a key monomer in synthesizing polycaprolactone (PCL), a polyester with excellent biocompatibility and flexibility. It is widely applied in biomedical fields such as drug delivery systems, tissue engineering scaffolds, and absorbable sutures due to its slow degradation rate in the body. In addition, it is utilized in the manufacture of biodegradable plastics, elastomers, and polyurethane resins for coatings, adhesives, and sealants. Its ability to blend with other polymers enhances material properties like toughness and processability, making it valuable in both industrial and specialty applications.
