Acrylate Polymer Production Process | E Plus Chemical

The acrylate polymer production process involves polymerizing acrylic monomers to form long-chain polymers, with variations in technique depending on the desired product form (emulsion, solution, or solid). The process typically begins with monomer preparation: selecting and purifying monomers such as 2-ethylhexyl acrylate, methyl acrylate, and acrylic acid, ensuring they meet purity standards (≥99%) to prevent polymerization disruptions. Emulsion polymerization, the most common method for water-based systems, involves dispersing monomers in water with surfactants to form micelles, then adding initiators (e.g., peroxides) to trigger polymerization at 60-90°C. This process produces stable emulsions used in adhesives and coatings, with E Plus Chemical Co., Ltd. utilizing fully automated lines to control temperature, agitation, and monomer addition rates for consistent particle size and viscosity. Solution polymerization dissolves monomers in organic solvents, using initiators to form polymers that are later stripped of solvent, suitable for high-solids coatings. Bulk polymerization, where monomers react without solvents, is used for solid polymers but requires careful heat management to prevent runaway reactions. Post-polymerization steps include neutralization (to adjust pH), filtration (to remove impurities), and addition of additives (e.g., defoamers, stabilizers). Quality control involves testing for molecular weight, viscosity, and solids content, with E Plus Chemical leveraging advanced catalytic polymerization technology to optimize polymer properties. The integrated production chain, from monomer synthesis to polymer formulation, ensures efficiency and quality, supporting large-scale production (240,000 tons/year for water-based resins at E Plus Chemical) to meet market demand.
