Poly(ethylene glycol) Diacrylate (PEGDA) is a fascinating chemical compound that bridges the gap between simple monomers and complex polymer networks. Its unique structure and reactivity make it a cornerstone in various advanced material applications, from advanced hydrogels to high-performance coatings. Understanding the science behind PEGDA—its synthesis, properties, and how it functions—is crucial for researchers and industrial formulators. As a leading manufacturer and supplier of high-purity PEGDA, we are pleased to shed light on this versatile chemical intermediate and guide you on where to buy it for your specific needs.

The synthesis of PEGDA typically involves the esterification of polyethylene glycol (PEG) with acrylic acid or its derivatives. This process yields a difunctional molecule, meaning it has two reactive acrylate groups at either end of the PEG chain. The length of the PEG chain, often specified by its average molecular weight (e.g., PEG400DA, PEG600DA), significantly influences the properties of the resulting polymer network. A shorter PEG chain generally leads to a stiffer, less flexible material, while a longer chain imparts greater flexibility and hydrophilicity.

Key properties of PEGDA include its appearance as a colorless to light yellow transparent liquid, a high purity (often ≥99.7%), low acidity, and minimal moisture content. These attributes are vital for controlled polymerization and the creation of precise material characteristics. The acrylate groups are highly reactive and readily undergo free-radical polymerization when initiated by UV light, heat, or other radical sources. This rapid curing capability is a major advantage in applications like UV-curable coatings, inks, and adhesives, as well as in 3D printing processes.

Industrially, PEGDA finds extensive application in the creation of hydrogels for biomedical purposes, such as tissue engineering scaffolds and controlled drug delivery systems. Its biocompatibility and ability to absorb significant amounts of water make it ideal for these sensitive applications. In the realm of advanced materials, PEGDA is a key component in photocurable resins used for 3D printing, enabling the fabrication of intricate prototypes and functional parts with excellent dimensional stability and mechanical integrity. It also enhances the flexibility, adhesion, and chemical resistance of various industrial coatings.
