Diisobutyl Phthalate (DIBP) — molecular structure

DIBP can be used as a plasticizer for PVC, with plasticizing efficiency comparable to dibutyl phthalate, though its volatility and water-extraction losses are greater; it can be used as a substitute for DBP. It is also used as a plasticizer for cellulosic resins, vinyl resins, nitrile rubber (NBR) and chloroprene rubber (CR). It is not suitable for agricultural film.
