2EHA High-Purity Acrylate Monomer | 50,000 Tons Annual Capacity

2-Ethylhexyl acrylate (2EHA) quality inspection is a rigorous process ensuring the monomer meets strict purity, performance, and safety standards, critical for its use in high-quality resins, adhesives, and coatings. Key inspection parameters include purity, with E Plus Chemical Co., Ltd. targeting 99% purity (verified via gas chromatography) to minimize impurities that could compromise polymerization or end-product properties. Moisture content is checked using Karl Fischer titration, as excess water can disrupt emulsion stability; acceptable levels are typically below 0.1%. Acidity, measured via titration, is monitored to ensure it remains within a specified range (e.g., <0.05% as acrylic acid), preventing corrosion in equipment or adverse reactions during polymerization. Color is assessed visually or with spectrophotometers, with clear, colorless to pale yellow 2EHA indicating high quality, as discoloration may signal degradation. Other tests include the determination of inhibitor content (to prevent premature polymerization during storage), density, and refractive index, which confirm chemical consistency. For safety, impurity screening identifies harmful compounds, ensuring compliance with regulatory limits. E Plus Chemical integrates quality inspection at every stage: raw material testing before production, in-process monitoring during catalytic polymerization, and final batch testing before release. Automated systems and calibrated instruments ensure accuracy, while documentation of results supports traceability. This stringent inspection process guarantees that 2EHA meets customer requirements and industry standards, enabling its reliable use as a key monomer in high-performance applications.
