At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing essential chemical raw materials that form the backbone of numerous industries. Among these, Dioctyl Phthalate (DOP) stands out as a versatile and highly sought-after plasticizer. Understanding its properties and applications is crucial for manufacturers looking to optimize their product formulations. As a prominent supplier of DOP in China, we are committed to delivering insights that empower our clients.

Dioctyl Phthalate (DOP) is an organic compound characterized by its colorless to light yellow, oily liquid appearance. Its molecular formula, C24H38O4, and a molecular weight of approximately 390.56 g/mol, contribute to its effectiveness as a plasticizer. Key physical properties include a density of about 0.98–0.99 g/cm³ at 20°C and a high boiling point of around 384°C, which translates to low volatility. This low volatility is a significant advantage, ensuring that DOP remains incorporated in the polymer matrix, thereby extending the product's lifespan and maintaining its flexibility over time. The mild, characteristic scent is also a notable feature. These attributes make DOP an ideal component for achieving desired material characteristics.

The primary application of DOP is as a plasticizer for polyvinyl chloride (PVC). It dramatically improves the flexibility, processability, and durability of PVC, transforming it from a rigid material into a pliable one. This is why DOP is widely used in PVC for products such as wire and cable insulation, synthetic leather, vinyl flooring, films, and coatings. Its excellent compatibility with PVC resins ensures a homogeneous blend, leading to consistent and reliable performance. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-quality DOP that adheres to strict industry standards, meeting the diverse needs of our clients.

Beyond PVC, DOP also finds important applications in other sectors. In the paints and coatings industry, it improves adhesion and flexibility. For adhesives and sealants, DOP enhances spreadability and long-term durability. It is also utilized in rubber and elastomers to provide elasticity and wear resistance, as well as in printing inks for smooth application and stability. The broad spectrum of these key applications for industrial use highlights DOP's indispensable nature. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to being a reliable partner, providing high-quality DOP to fuel innovation and manufacturing excellence across these varied industries.
