Acrylate Emulsion Production Process | E Plus Chemical

The acrylate emulsion production process involves a series of controlled steps to ensure the synthesis of high-quality, consistent polymer dispersions. It begins with the preparation of raw materials, including acrylic monomers such as 2-ethylhexyl acrylate (2EHA) with 99% purity, water, emulsifiers, initiators, and additives. These materials are carefully measured and mixed to form a pre-emulsion, where monomers are dispersed as small droplets in water with the help of emulsifiers, which stabilize the droplets to prevent coalescence. The main polymerization reaction occurs in a reactor, where the pre-emulsion is gradually added under controlled temperature conditions (typically 60-90°C). Initiators, such as peroxides or azo compounds, are introduced to trigger free radical polymerization, causing monomers to form polymer chains that grow into particles. Throughout the reaction, parameters like temperature, agitation speed, and feed rates are closely monitored using fully automated systems, such as those employed by E Plus Chemical Co., Ltd., to ensure uniformity and prevent issues like agglomeration or incomplete polymerization. After polymerization, the emulsion undergoes post-treatment steps, including pH adjustment to optimize stability, addition of preservatives to inhibit microbial growth, and filtration to remove any large particles or impurities. The finished product is then tested for key properties such as viscosity, solids content, particle size distribution, and adhesion to ensure it meets quality standards. E Plus Chemical leverages advanced catalytic polymerization technology and an integrated industrial chain—from monomer synthesis to emulsion production—to streamline this process, achieving high efficiency and consistent quality. This production process supports the company’s annual capacity of 240,000 tons of acrylic water-based resins, including acrylate emulsion, and enables customization through OEM services to adjust formulations for specific applications in coatings, adhesives, and more.
