At NINGBO INNO PHARMCHEM CO.,LTD., we understand that in-depth knowledge of product specifications is crucial for informed decision-making. Dioctyl Terephthalate (DOTP) plasticizer is one such product whose unique properties make it a preferred choice in numerous industries. Let's delve into the detailed benefits and characteristics of DOTP.

Chemically, DOTP is a diester of terephthalic acid and 2-ethylhexanol. This composition distinguishes it from phthalate-based plasticizers, positioning it as a safer and more environmentally sound option. Its molecular formula, C24H38O4, and molecular weight of approximately 390.56 g/mol indicate a robust structure capable of imparting significant flexibility to polymers.

The physical properties of DOTP are highly advantageous. It is typically a clear, colorless, and viscous liquid with a subtle odor. A key attribute is its low volatility, which means it evaporates less readily than many other plasticizers. This low volatility ensures that the plasticizer remains within the material over a longer period, extending the product's lifespan and maintaining its flexibility. This is particularly important when considering applications such as cable materials or automotive parts that are exposed to varying temperatures.

Furthermore, DOTP exhibits excellent resistance to extraction by water and soap. This property is critical for applications where the plasticized material might come into contact with aqueous solutions or cleaning agents. It prevents the plasticizer from leaching out, thus preserving the material's integrity and performance characteristics.

The electrical insulation properties of DOTP are another significant advantage. It possesses a high volume resistivity, making it an ideal choice for electrical wire and cable insulation. This contributes to the safety and reliability of electrical products, especially those operating at higher temperatures or under demanding conditions.

When comparing DOTP to its phthalate counterparts, such as DOP, the benefits become clearer. DOTP is not classified as a hazardous substance under many regulatory frameworks, unlike some phthalates which have raised concerns regarding potential health effects, including endocrine disruption. This phthalate-free nature makes DOTP a more sustainable and consumer-friendly choice, especially for products intended for close human contact, such as children's toys, food packaging, and medical devices.

The plasticizing efficiency of DOTP is also noteworthy. It effectively reduces the glass transition temperature of PVC, rendering it more pliable and easier to process. This allows manufacturers to employ various processing techniques, including extrusion, calendering, and injection molding, to create a wide range of products from flexible films and artificial leather to automotive components and flooring materials.

At NINGBO INNO PHARMCHEM CO.,LTD., we ensure that our DOTP plasticizer meets the highest purity standards, typically 99.5% or higher. This commitment to quality guarantees consistent performance and reliability for our clients. By understanding these detailed properties, manufacturers can confidently integrate DOTP into their product development to achieve superior results.
