The main use of Dioctyl phthalate

Dioctyl phthalate is a general-purpose plasticizer mainly used for processing polyvinyl chloride grease, and also for processing high-polymer resins such as resin, acetate resin, ABS resin and rubber. It can also be used in paints, dyes and dispersants. Etc, Dioctyl phthalate plasticized PVC can be used to make artificial leather, agricultural film, packaging materials, cables and so on.
Dioctyl phthalate is the most widely used plasticizer in the industry. It has good compatibility with most industrial synthetic resins and rubbers except cellulose acetate and polyvinyl acetate. Dioctyl phthalate has good comprehensive properties, good mixing performance, high plasticizing efficiency, low volatility, good low temperature softness, water resistance, high electrical performance, good heat resistance and weather resistance.
In HVAC, it is used to test the filtration efficiency of high efficiency filters. Because 0.3um (micron) is the most transparent particle size for high efficiency filters, Dioctyl phthalate is used to test the filtration efficiency of high efficiency filters.
