The formula of 2-ethylhexyl acrylate (2EHA) is chemically represented as C11H20O2, reflecting its composition of 11 carbon atoms, 20 hydrogen atoms, and 2 oxygen atoms. This formula corresponds to a molecular structure consisting of an acrylate group (CH2=CH-COO-) covalently bonded to a 2-ethylhexyl ester group (-(CH2)3CH(C2H5)CH2CH3), a branched alkyl chain that imparts unique properties to the monomer. The acrylate group contains a reactive double bond (C=C), which is critical for polymerization reactions, allowing 2EHA to copolymerize with other monomers (such as methyl acrylate or styrene) to form acrylic polymers used in adhesives, resins, and coatings. The 2-ethylhexyl chain contributes to 2EHA’s hydrophobicity, low glass transition temperature (Tg), and flexibility, characteristics that enhance the performance of polymers derived from it—improving their ability to withstand temperature changes, resist water, and maintain adhesion. E Plus Chemical Co., Ltd. produces 2EHA with this precise chemical formula, ensuring 99% purity through advanced catalytic polymerization and purification processes, which remove impurities that could alter the formula or disrupt polymerization. The consistency of this formula across batches is maintained via strict quality control, making 2EHA a reliable building block for manufacturers seeking predictable performance in their formulations, whether for flexible medical tapes or durable outdoor coatings.
