Poly(ethylene glycol) dimethacrylate is widely used in the production of hydrogels, which are essential in biomedical applications such as drug delivery systems, tissue engineering, and wound dressings. Its ability to form cross-linked networks with high water content makes it suitable for creating biocompatible and flexible materials. In the field of contact lenses, it is utilized to develop soft, oxygen-permeable lenses that enhance comfort for users. Additionally, it serves as a key component in the fabrication of dental materials, including restorative composites and adhesives, due to its durability and ease of polymerization. In industrial applications, it is employed as a cross-linking agent in coatings, adhesives, and sealants, providing enhanced mechanical properties and stability. Its versatility also extends to the development of controlled-release systems in agriculture, where it helps in the gradual release of fertilizers or pesticides.
