4-arm PEG-Acrylate

Price range: $300.00 through $1,200.00

4-arm PEG-Acrylate is a multi-arm polyethylene glycol derivative containing four terminal acrylate groups attached to a central core. The acrylate functionalities readily participate in free-radical polymerization, photopolymerization, Michael addition, and hydrogel crosslinking reactions. 4-arm PEG-Acrylate is widely used in hydrogel formation, tissue engineering, drug delivery, bioinks, regenerative medicine, and biomaterials research.

Description

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.
