Survey of plasticizers for vinyl resins

Abstract

For satisfactory performance in vinyl chloride‐acetate resins, plasticizer must be compatible with the resin in a wide range of concentration. Low volatility low rates of extraction by oil and water, and good chemical stability are necessary in most applications. In special applications good electrical properties, low flammability, preservation of compound flexibility at low temperatures, and freedom from odor and taste are also required. Physical test methods, suitable for the evaluation of plasticizers, are briefly described.
