Product Introduction
What Is Poly(Ethylene Glycol) Diacrylate
Poly(ethylene glycol) diacrylate (PEGDA) is a polymer obtained by the polymerization of ethylene glycol diacrylate (EGDA). Ethylene glycol diacrylate is a diacrylate derivative of ethylene glycol, which has two acrylate groups (-CH2=CHCOO-) attached to the two ends of the ethylene glycol molecule.Poly(ethylene glycol) diacrylate is commonly used in the field of polymer chemistry as a crosslinkable resin. The acrylate groups in PEGDA can undergo radical polymerization reactions, which allows PEGDA to be crosslinked with other polymers or monomers to form networks or polymers with desired properties. Crosslinked PEGDA polymers are known for their hydrophilicity, biocompatibility, and low toxicity, making them suitable for various applications, including biomedical, drug delivery, and tissue engineering.

Advantages of Poly(Ethylene Glycol) Diacrylate
Hydrophilicity
PEGDA is highly hydrophilic, which means it can attract and retain water. This property makes PEGDA suitable for applications involving water, such as biomedical, drug delivery, and tissue engineering.
Biocompatibility
PEGDA is biocompatible, meaning it is non-toxic and non-immunogenic to living cells and tissues. This property makes PEGDA suitable for biomedical applications, such as implantable devices and scaffolds for tissue regeneration.
Low toxicity
PEGDA is relatively non-toxic and has low acute toxicity. This property makes PEGDA suitable for applications involving contact with living organisms, such as cosmetics and food packaging.
UV curing
PEGDA can be cured using ultraviolet (UV) radiation, which allows for rapid curing and crosslinking of PEGDA polymers. This property makes PEGDA suitable for applications that require fast curing, such as 3D printing and adhesives.
Solubility
PEGDA is soluble in a variety of solvents, including water, organic solvents, and polar solvents. This property makes PEGDA suitable for applications that require solubility in specific solvents, such as paints, coatings, and inks.
Versatility
PEGDA can be modified and functionalized to introduce specific chemical groups or properties. This property makes PEGDA suitable for applications that require specific functionalities, such as sensors and catalysts.
Types of Poly(Ethylene Glycol) Diacrylate
Low molecular weight PEGDA has a relatively low molecular weight, typically in the range of a few hundred to a few thousand Daltons. Low molecular weight PEGDA is more soluble in water and organic solvents and has lower viscosity. It is commonly used in applications such as adhesives, coatings, and inks.
Medium molecular weight PEGDA has a molecular weight in the range of several thousand to tens of thousands Daltons. Medium molecular weight PEGDA has higher viscosity and is less soluble in water but more soluble in organic solvents. It is commonly used in applications such as adhesives, coatings, and composites.
High molecular weight PEGDA has a very high molecular weight, typically in the range of hundreds of thousands to millions of Daltons. High molecular weight PEGDA has very high viscosity and is almost insoluble in water but soluble in organic solvents. It is commonly used in applications such as composites, adhesives, and membranes.
Functionalized PEGDA is PEGDA that has been modified with specific chemical groups to introduce specific functionalities. For example, PEGDA can be modified with amino groups, carboxyl groups, or thiol groups to introduce specific chemical reactions or properties. Functionalized PEGDA is commonly used in applications such as sensors, catalysts, and drug delivery.
Branched PEGDA is PEGDA that has been modified with branches to introduce a more complex molecular structure. Branched PEGDA has a lower viscosity and better solubility than linear PEGDA. It is commonly used in applications such as adhesives, coatings, and composites.

How to Maintain Poly(Ethylene Glycol) Diacrylate
Store properly: PEGDA should be stored in a cool, dry place away from direct sunlight. Exposure to heat, moisture, and ultraviolet radiation can degrade the quality and stability of PEGDA.
Handle with care: When handling PEGDA, avoid prolonged exposure to skin and avoid inhalation of dust or vapors. Wear appropriate protective equipment, such as gloves and a mask, to minimize contact with the material.
Use appropriate tools and equipment: When working with PEGDA, use tools and equipment suitable for handling chemicals. Avoid using metal tools that can react with PEGDA and cause degradation.
Follow safety procedures: Before using PEGDA, read and follow the manufacturer's safety instructions and handling procedures. Understand the potential hazards and take appropriate precautions to ensure your safety.
Keep away from incompatible substances: PEGDA may be incompatible with certain substances. Avoid mixing PEGDA with reactive substances, strong acids, bases, or other chemicals that may react or cause degradation.
Regular inspection and testing: Regularly inspect the quality and stability of PEGDA to ensure it meets the required standards. If there are any signs of degradation, contamination, or expiration, discontinue use and replace it with fresh material.
What Is the Working Principle of an Poly(Ethylene Glycol) Diacrylate
Adhesives and sealants
When PEGDA is used as an adhesive or sealant, it undergoes a curing reaction. The acrylate groups in PEGDA can react with each other or with other compounds through radical polymerization, resulting in the formation of a crosslinked polymer network. This crosslinking process provides strength and adhesion to the bond or seal.
3D.3D print
In 3D printing using PEGDA, resins containing PEGDA are exposed to ultraviolet (UV) radiation. Ultraviolet radiation activates the acrylate groups in PEGDA, initiating a polymerization reaction that solidifies the resin layer by layer. This allows the construction of three-dimensional objects by controlling the curing process.
Tissue engineering
In tissue engineering, PEGDA can be used to fabricate scaffolds for cell culture and tissue regeneration. PEGDA's biocompatibility and hydrophilicity allow cells to attach, grow, and differentiate on the scaffold. The crosslinking process of PEGDA can control the porosity and mechanical properties of the scaffold.
Drug delivery
In drug delivery applications, PEGDA can be used to encapsulate or conjugate drugs. The hydrophilic properties of PEGDA can help improve the solubility and stability of drugs, while the crosslinking process can control the release rate of drugs.
How to Choose the Poly(Ethylene Glycol) Diacrylate Correctly
