In the realm of industrial chemistry, monomers serve as the fundamental building blocks for a vast array of polymers and materials. Among these, 2-Hydroxyethyl Acrylate (HEA), with the chemical formula C5H8O3 and CAS number 818-61-1, is a particularly versatile and valuable compound. Its unique structure, featuring both a reactive acrylate ester and a primary alcohol group, unlocks a wide spectrum of applications. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier, is at the forefront of providing high-quality HEA to industries worldwide.

Chemical Profile of HEA:

HEA is typically synthesized through the esterification of acrylic acid with ethylene oxide. This process yields a clear, colorless liquid with a characteristic ester odor. Key chemical properties that drive its industrial demand include:

  • Polymerizability: The vinyl group (-CH=CH2) readily undergoes free-radical polymerization, allowing HEA to be incorporated into polymer chains, either as a homopolymer or, more commonly, as a comonomer with other acrylates, methacrylates, vinyl monomers, or styrenics.
  • Hydroxyl Reactivity: The primary hydroxyl group (-OH) offers a site for further chemical reactions. It can participate in esterification, etherification, and urethane formation, enabling the synthesis of functionalized polymers, crosslinked networks, and grafted copolymers.
  • Hydrophilicity: The presence of the hydroxyl group imparts a degree of polarity and hydrogen-bonding capability, leading to increased hydrophilicity in polymers compared to their non-hydroxylated counterparts.
  • Low Volatility: Compared to smaller acrylate esters, HEA exhibits lower volatility, which can be advantageous in handling and processing.

Diverse Industrial Applications:

The dual functionality of HEA translates into its widespread use across several key industries. As a manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. supplies HEA for applications such as:

  • Thermosetting Coatings: HEA is a crucial component in acrylic resins for coatings that cure via crosslinking reactions. It enhances adhesion, flexibility, and chemical resistance in automotive, industrial, and architectural coatings.
  • Adhesives and Sealants: Its ability to improve bond strength and cohesion makes HEA a valuable monomer in the formulation of high-performance adhesives and sealants, including pressure-sensitive adhesives.
  • Synthetic Rubbers and Elastomers: HEA can be used to modify the properties of synthetic rubbers, imparting improved thermal stability and processing characteristics.
  • Paper and Textile Treatment: In paper processing, it can enhance water resistance and strength. In textiles, it can improve dyeability and finishing properties.
  • Radiation Curing: HEA functions as a reactive diluent in UV and electron beam curing systems, helping to lower viscosity and accelerate the curing rate.
  • Biomedical Applications: Due to its hydrophilic nature and biocompatibility, HEA is also explored for use in hydrogels for drug delivery and medical devices.
