Product Description

Poly(ethylene glycol) diacrylate (PEGDA 400)

Poly(ethylene glycol) diacrylate (PEGDA) is a bifunctional macromer with terminal acrylate groups that can form crosslinked polymer networks via free-radical polymerization under appropriate initiation conditions. The PEG backbone contributes hydrophilicity and is commonly selected in research where water compatibility and tunable network properties are important.

PEGDA is available in multiple molecular weights. In general, molecular weight influences crosslink density and resulting material characteristics (such as swelling behavior and mechanical response) in crosslinked systems. PEGDA 400 refers to a PEGDA grade with an average molecular weight around 400.

FAQs

Common questions about Poly(ethylene glycol) diacrylate (PEGDA 400).

What is PEGDA 400?

PEGDA 400 is a poly(ethylene glycol) diacrylate grade with an average molecular weight around 400. It is a bifunctional macromer with acrylate end groups used to form crosslinked polymer networks.
What does “diacrylate” mean for PEGDA?

“Diacrylate” indicates there are two acrylate functional groups—typically one at each end of the PEG chain. These groups can participate in free-radical reactions to form crosslinked networks.
How does PEGDA form hydrogels?

When PEGDA is polymerized under suitable conditions, its acrylate groups can crosslink to create a network that can absorb water. Hydrogel properties depend on formulation and curing conditions.
How does molecular weight affect PEGDA networks?

Molecular weight can influence crosslink density and network structure. In general terms, different PEGDA molecular weights can yield different swelling behavior and mechanical response in the resulting polymer networks, depending on the overall formulation.
Is PEGDA 400 water soluble?

PEG-based materials are typically hydrophilic and often compatible with water. Actual solubility and handling can depend on the specific grade, temperature, and formulation components.
