⟡ PEGDA 10K / Hydrogel Crosslinkers / Biomaterials Research
Poly(ethylene glycol) diacrylate (PEGDA 10K) is a hydrophilic bifunctional macromer containing terminal acrylate groups that enable rapid crosslinking through free-radical polymerization. Its polyethylene glycol backbone provides water solubility, flexibility, and biocompatibility, making PEGDA widely used in hydrogel systems, biomaterials research, photopolymerization, and advanced polymer engineering applications.
PEGDA 10K is commonly selected for applications requiring highly hydrated hydrogel networks, tunable swelling behavior, and soft mechanical properties. The higher molecular weight of PEGDA 10K supports lower crosslink density and increased mesh size, making it useful for tissue engineering, diffusion-sensitive systems, and soft biomaterial architectures.

Typical Applications
Hydrogel formation
PEGDA 10K is widely used to create soft hydrogels for tissue engineering, controlled release systems, wound healing research, and biomaterial scaffolds.
3D printing & photopolymerization
Commonly incorporated into photocurable bioinks and resin formulations for bioprinting and precision hydrogel fabrication.
Microfluidics & lab-on-a-chip systems
PEGDA crosslinked matrices are used to fabricate hydrogel membranes, microchannels, and flexible analytical device structures.
Coatings & surface modification
Utilized in hydrophilic coatings and crosslinked polymer layers where water compatibility and controlled permeability are important.
Functional Properties
The polyethylene glycol backbone contributes hydrophilicity, flexibility, and low protein adsorption characteristics, while the terminal acrylate groups allow rapid polymer network formation under UV or radical initiation conditions.
Compared to lower molecular weight PEGDA materials, PEGDA 10K generally produces softer hydrogel structures with larger mesh sizes, lower crosslink density, and increased swelling capacity. These characteristics are especially useful for diffusion-sensitive biomaterials and soft matrix applications.
Why Use PEGDA 10K?
PEGDA 10K is commonly selected for hydrogel and polymer engineering applications requiring soft material mechanics, tunable permeability, and highly hydrated polymer networks. Researchers frequently use PEGDA systems to control hydrogel stiffness, swelling behavior, and molecular transport characteristics.
Its compatibility with photopolymerization methods and biofabrication workflows makes PEGDA 10K a versatile material for advanced biomaterials science, biomedical engineering, and soft polymer research.
