DescriptionDiisobutyl phthalate (DIBP) is a specialist plasticizer often used in combination with other high molecular weight phthalates. It is a fast fusing plasticizer which by itself it is too volatile for PVC applications. It is frequently used as a gelling aid in combination with other plasticizers. ApplicationsIt is one kind of colorless transparent oily liquid. Relative Density (d2020) 1.040. Dissolved in cellulose acetate, polyvinyl chloride resins and most of resins. It can be used as the toughening agent of cellulose resin, vinyl resin, nitrile rubber, chlorinated rubber. Its plasticizing capacity is similar to DBP, but its volatility and moisture are larger than DBP. It can be used as a substitute for DBP with toxicity coefficient T = 500, it is not suitable for PVC film.
