Benzoate plasticizers for reducing plastisol viscosity and fusion temperature
Viscosity control of plastisols is a major consideration in the formulation of a vinyl product produced by methods such as spread or reverse roll coating. The application conditions often dictate the addition of a diluent in the formulation to lower the rheology of the plastisol for successful processing. A benzoate plasticizer has been introduced that has the capability of lowering plastisol viscosity while also performing as a highly solvating plasticizer. This unique combination is illustrated in both phthalate and benzoate containing plastisols and the properties of both the plastisol and the final sheet are presented.
