The main use of dioctyl phthalate

Dioctyl phthalate is a universal plasticizer , and is mainly for the processing of polyvinyl chloride resin, but also for land based resins, acetate resins, ABS resins and rubber processing of polymers, can also be used in making paints , dyes, dispersing agents, DOP plasticized PVC can be used to make leather, agricultural films, packaging materials, cables.

Dioctyl phthalate is the industry the most widely used plasticizer, in addition to cellulose acetate, polyvinyl acetate, but the vast majority of industrial use of synthetic resins and rubbers have good compatibility. This product has a good overall performance, good mixing performance, plasticized high efficiency, low volatility, good low temperature flexibility, water extraction, electrical properties, heat resistance and weather resistance.

In HVAC, HEPA filter for testing filtration efficiency. Because for high efficiency filter, 0.3um (micron) is the largest particle penetration, hence the dioctyl phthalate to test the efficiency filter filtration efficiency.
