Diisobutyl Phthalate

Diisobutyl Phthalate (DIBP) is a colorless oily liquid with a slight ester odor. It is a plasticizer that is used in nitrocellulose, alkyd resin paints, inks, coatings, lacquers, and adhesives. Due to lower production costs, DIBP is used as an alternative to DBP (Dibutyl Phthalate).

ArChem provides Diisobutyl Phthalate and other plasticizers such as Acetyl triethyl citrate (ATEC), Dioctyl Adipate (DOA), and Dibutyl Phthalate (DBP) for various industrial applications. Additionally, ArChem provides customers with other chemical products including Nitrocellulose, Nitrocellulose solution, organic solvents, etc. for further information please contact our technical sales team in ArChem.
