Poly(ethylene glycol) diacrylate (PEGDA) is a versatile specialty chemical widely used across various industries. In biomedical applications, it is employed in the development of hydrogels due to its biocompatibility and ability to form crosslinked networks. It is commonly used in tissue engineering to create scaffolds that mimic the extracellular matrix, promoting cell growth and tissue regeneration. Additionally, PEGDA is utilized in drug delivery systems to design controlled-release carriers, ensuring sustained and targeted release of therapeutic agents. In photopolymerization processes, it serves as a key component in 3D printing and microfabrication, enabling the creation of complex, high-precision structures. Its hydrophilic nature makes it suitable for surface modification, enhancing wettability and biocompatibility of medical devices. Beyond biomedicine, PEGDA is applied in the production of adhesives, coatings, and other materials, leveraging its excellent cross-linking properties to achieve flexibility, durability, and customizable physical characteristics.
