Polyethylene glycol diacrylate (PEGDA 4000)

Poly(ethylene glycol) diacrylate (PEGDA) is a bifunctional macromer with terminal acrylate groups, allowing it to form robust crosslinked networks via free-radical polymerization. Its hydrophilic backbone, PEG backbone imparts water solubility and biocompatibility, making PEGDA ideal for applications requiring precise control over mechanical and swelling properties. PEGDA is available in various molecular weights, enabling tailored crosslink densities and material characteristics.
PEGDA’s versatility, hydrophilicity, and biocompatibility make it an essential material for innovative applications such as:

Hydrogels: Widely used in tissue engineering scaffolds, drug delivery systems, and wound dressings for its biocompatibility and tunable properties.
3D Printing: Key ingredient in photocurable resins for precision biofabrication, allowing for the creation of complex structures with controlled swelling and stiffness.
Microfluidics: Forms crosslinked matrices for creating channels and membranes in lab-on-a-chip devices.
Coatings and Adhesives: Provides strong adhesion and hydrophilic surface coatings for medical and industrial use.
