Dibutyl Phthalate (DBP), identified by CAS number 84-74-2, is a staple chemical in numerous industrial sectors, prized for its dual functionality as a plasticizer and solvent. For professionals involved in manufacturing and product development, a thorough understanding of DBP's characteristics and market availability is essential. This overview aims to provide industrial buyers with key insights into Dibutyl Phthalate, from its technical specifications to reliable sourcing strategies.

As a colorless, oily liquid with a mild odor, Dibutyl Phthalate is chemically known as dibutyl benzene-1,2-dicarboxylate. Its molecular formula, C16H22O4, and molecular weight of approximately 278.34 g/mol define its physical and chemical behavior. DBP is soluble in most organic solvents but exhibits low solubility in water. Its relatively high boiling point (around 340°C) and flash point (around 157°C) contribute to its utility in various processing conditions.

The primary industrial application of DBP is as a plasticizer, particularly for polyvinyl chloride (PVC) resins. It significantly enhances the flexibility, durability, and processability of PVC, making it suitable for a wide range of products, including flooring, cables, films, and automotive components. Beyond PVC, DBP is also used in the rubber industry to improve elasticity and in various resin systems. Its solvent properties are leveraged in the formulation of coatings, adhesives, printing inks, and lacquers, where it helps improve flow, dispersion, and adhesion.

When considering industrial procurement, identifying a dependable supplier or manufacturer of Dibutyl Phthalate is paramount. Buyers often seek out suppliers who can guarantee high purity (typically 99% minimum), consistent product quality, and competitive price points, especially when purchasing in bulk. Companies based in China are often prominent suppliers due to their large-scale production capabilities. It is advisable to request detailed product specifications, safety data sheets (SDS), and inquire about their quality control processes before making a purchase decision.

While DBP is a valuable industrial chemical, it's important for buyers to be aware of its regulatory status and associated health and environmental considerations. Certain jurisdictions have placed restrictions on DBP use in specific consumer products, such as children's toys and cosmetics. However, for its core industrial applications, where performance benefits are critical and controlled, DBP remains a widely accepted and utilized material. Responsible handling and adherence to safety guidelines are always recommended when working with industrial chemicals.

To effectively buy Dibutyl Phthalate, engage with suppliers who offer a combination of quality products, reliable logistics, and responsive customer service. Whether you are formulating new products or ensuring the continuity of existing production lines, a strong partnership with a DBP supplier will be instrumental in achieving your manufacturing goals.
