Poly(ethylene glycol) dimethacrylate is widely used in the production of hydrogels due to its ability to form cross-linked networks when polymerized. 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 the fabrication of contact lenses and other ophthalmic devices, offering high water content and biocompatibility. In tissue engineering, this chemical serves as a scaffold material, promoting cell growth and tissue regeneration. It is also employed in the development of adhesives and coatings, providing flexibility and durability. Furthermore, its use in photolithography and 3D printing enables the creation of precise and complex structures for various industrial applications.
