Product Overview
PVC paste resin, as the nomenclature implies, is engineered to achieve specialized rheological properties suitable for paste-form applications. This material finds principal application in plastisol systems - a colloidal dispersion characterized by micron-sized PVC particles homogenously distributed within a plasticizer matrix. The production of these specialized resins employs emulsion or microsuspension polymerization methodologies, processes specifically designed to achieve precise particle size distributions and surface area characteristics. This morphological precision ensures optimal plasticizer absorption kinetics, resulting in stable colloidal suspensions that demonstrate superior viscosity profiles, extended pot life, and enhanced end-product performance across diverse coating, dipping, and rotational molding applications.
