General Description
4-arm PEG-Acrylate is a branched PEG macromer designed for hydrogel synthesis and advanced biomaterials applications. Compared with linear PEG derivatives, the four-arm architecture provides higher functional group density, enhanced crosslinking efficiency, and improved network formation.
The terminal acrylate groups readily react with thiols, amines, and other vinyl-reactive species and can undergo UV-initiated or visible-light photopolymerization to form highly hydrated hydrogel networks. The PEG backbone provides excellent water solubility, flexibility, biocompatibility, and resistance to nonspecific protein adsorption.
4-arm PEG-Acrylate is frequently employed in injectable hydrogels, tissue engineering scaffolds, cell encapsulation, 3D bioprinting, drug delivery systems, wound healing materials, and regenerative medicine applications.
