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 swelling and release properties. In the field of contact lenses, it is utilized to manufacture soft, biocompatible lenses that provide comfort and oxygen permeability. Additionally, it serves as a key component in the fabrication of photopolymerizable resins for 3D printing, enabling the creation of precise and complex structures. Its versatility also extends to coatings and adhesives, where it enhances flexibility and durability.
