CAS 10311-7: 2-Ethylhexyl Acrylate - High Purity | E Plus Chemical

The physical properties of CAS 103117 (2-ethylhexyl acrylate, 2EHA) define its handling characteristics and performance in applications, making them critical for formulation and processing. 2EHA is a clear, colorless to pale yellow liquid with a mild, characteristic odor, visually distinguishable by its low viscosity (typically 1-5 mPa·s at 25°C), enabling easy pumping and mixing in production. Its density is 0.885-0.895 g/cm³ at 25°C, lighter than water, affecting mixing ratios in formulations. The refractive index—1.435-1.440 at 25°C—indicates light-bending properties, useful for quality checks. As a flammable liquid, it has a flash point of 60-70°C (closed cup) and a boiling point of approximately 215-218°C, dictating storage and transportation requirements. Vapor pressure is low (0.1-0.5 mmHg at 25°C), reducing vapor exposure risks but requiring adequate ventilation. 2EHA is insoluble in water but soluble in organic solvents (ethanol, acetone, toluene), influencing its use in solvent-based formulations. Freezing point is below -90°C, ensuring it remains liquid in cold environments. E Plus Chemical Co., Ltd.’s 99% pure CAS 103117 2EHA consistently meets these physical property specifications, verified via batch testing, ensuring predictable behavior in polymerization, coating application, and adhesive formulation processes.
