    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
    Packed in iron drum,net weight 180 kg/drum.Stored at dry,shady,ventilated place. Prevented from collision
    and sunrays,rain-attack during handling and shipping.
