Product Description
Dibutyl Phthalate (DBP), identified by CAS number 84-74-2, is a dibutyl ester of phthalic acid, also known as di-n-butyl phthalate. This colorless, odorless oily liquid serves as a primary plasticizer for cellulose resins and polyvinyl chloride (PVC). Notably, DBP is particularly effective in cellulose nitrate coatings due to its excellent solubility, dispersion, and adhesion properties. However, it possesses high volatility and oil extraction capabilities, which can impact durability. Manufacturers and factories in China typically produce Dibutyl Phthalate from phthalic anhydride and butanol. At Integratechem, we are proud to be a leading manufacturer and supplier of high-quality DBP, catering to clients and suppliers in China and beyond.

Applications & Advantages
Dibutyl Phthalate (CAS No 84-74-2), or di-n-butyl phthalate, is primarily utilized as a main plasticizer for cellulose resins and PVC. Its superior solubility and adhesion properties make it ideal for cellulose nitrate coatings. Manufacturers and factories commonly use DBP in the production of colored films, artificial leather, and various plastic products. It also acts as a plasticizer and softener for both natural and synthetic rubber, enhancing product resilience. However, it is important to note its volatility and oil extraction properties may limit durability. Furthermore, DBP finds applications in paints and coatings.
Packaging, Storage, and Transport
Dibutyl Phthalate is packaged in iron drums, with a net weight of 200 kg per barrel. For optimal storage, keep the product in a well-ventilated and dry area to prevent water intrusion. Due to its flammable nature, it is crucial to store away from ignition sources. All storage and transportation should comply with general flammable chemicals regulations, maintaining a storage temperature between 2 °C and 8 °C.
