Product Usage

This product is the main plasticizer for polyvinyl chloride. Compared with dioctyl phthalate, its compatibility and plasticizer efficiency are slightly better, and its tensile strength, elongation, and cold resistance are generally the same, but its volatility is relatively high. This product can also be used in vinyl chloride copolymers, nitrocellulose paints, and various rubbers.
