邻苯二甲酸二丁酯 High Purity Dibutyl Phthalate (DBP)

Dibutyl Phthalate (DBP, CAS 84-74-2) is a premium, colorless, and transparent oily liquid presenting a mild, characteristic aromatic odor. It is insoluble in water but completely miscible with major organic solvents such as ethanol, ether, acetone, and benzene. As a highly efficient, general-purpose primary plasticizer in the macromolecule and chemical processing industry, DBP exhibits outstanding solubility, compatibility, and cohesion with polyvinyl chloride (PVC), nitrocellulose, ethylcellulose, and polyvinyl acetate resins. It effectively imparts superior flexibility, elasticity, and processing fluidity to polymer products. Additionally, DBP acts as a critical flexible modifier and high-performance solvent in formulating industrial adhesives, coatings, specialty inks, and dye intermediates.

Technical Specifications & Physical Properties

Core Applications

• Flexible PVC & Polymer Compounds: Extensively utilized in processing flexible polyvinyl chloride (PVC) products, including industrial hoses, plastic sheets, synthetic leathers, advanced films, and polymer consumer goods.

• Cellulose Coatings & Fine Lacquers: Serves as a vital plasticizer in nitrocellulose and ethylcellulose coatings to deliver excellent film flexibility, bending resistance, adhesion, and gloss.

• Advanced Industrial Adhesives: Deployed in polyvinyl acetate (PVAc) emulsions, industrial sealants, and glues to greatly improve primary tack, flexibility, and anti-aging qualities.

• Rubbers, Printing Inks & Fixatives: Applied as a rubber softener to optimize compounding rheology; used as an auxiliary solvent and film-forming agent in printing inks, smokeless powders, and as a steady fixative in specialized fragrance blends.

Packaging & Storage

Packing: Standard shipping weight is 200 KGS net per drum. Bulk 1000 KGS IBC tanks and large-scale bulk ISO TANK containers are fully available for commercial export orders.

Storage: Store within a cool, dry, and optimally ventilated specialized chemical storage zone. The ambient storage temperature should not exceed 30°C. Keep far away from flames, sparks, and direct sunlight. Keep all containers securely sealed and separate from powerful oxidizers and strong bases.
