    Dioctyl sebvacate uses

    DOS plasticizer is a superior cold-resisting plasticizer,it has good plasticizing effect and

    better heat endurance,light-resisting and electrical properties. It is chiefly used in processing polyvinl

    chloride and its copolymer,cellulosic resins and synthetic rubbers,etc..It is usually mixed with phthalic

    esters in use to minimize its migration rate.


    Package and storage
