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.
