This PVC termination agent is a stable transparent or white emulsion, made from a multi-component compound using advanced production processes (physical properties may vary depending on the grade). It is widely used in the suspension polymerization process of PVC, primarily to terminate the polymerization reaction in the later stages. It is added when the polymerization pressure drops to 0.05-0.15 MPa. The optimal usage amount is adjusted based on factors such as production process conditions, resin type, monomer type, initiator variety, and their respective quantities, ensuring effective termination of the polymerization reaction while minimizing costs. Its main characteristics include strong polymerization termination ability with significant effects, high whiteness, and excellent dispersibility, making it easy to operate and use.
