Poly(ethylene glycol) diacrylate is widely used in the production of hydrogels due to its ability to form cross-linked networks when exposed to light or heat. These hydrogels are essential in biomedical applications, such as drug delivery systems, where they provide controlled release of therapeutic agents. Additionally, it is utilized in tissue engineering to create scaffolds that support cell growth and regeneration. In the field of 3D printing, this chemical serves as a key component in photopolymer resins, enabling the creation of precise and complex structures. It is also employed in the development of contact lenses and other medical devices, offering biocompatibility and flexibility. Furthermore, its use in coatings and adhesives enhances material durability and performance in various industrial applications.
