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 makes it suitable for creating materials with controlled porosity and swelling properties.

In the field of ophthalmology, it is utilized in the development of contact lenses and intraocular lenses due to its biocompatibility and flexibility. Additionally, it serves as a key component in the synthesis of polymers for coatings and adhesives, providing enhanced durability and adhesion properties.

In research, it is employed as a monomer in photopolymerization processes, enabling the fabrication of microfluidic devices and 3D-printed structures. Its versatility and tunable properties make it a valuable material in both industrial and scientific applications.
