Dioctyl Terephthalate, commonly known as DOTP, stands as a prominent and highly effective plasticizer widely utilized across numerous industries. As a key product offered by NINGBO INNO PHARMCHEM CO.,LTD., DOTP is recognized for its exceptional performance characteristics and its favorable environmental profile, positioning it as a preferred alternative to conventional phthalate plasticizers like DOP and DINP.

Chemically, DOTP is the diester of terephthalic acid and 2-ethylhexanol. This structure imparts specific properties that make it particularly valuable in demanding applications. Unlike many traditional plasticizers derived from ortho-phthalic acid, DOTP originates from para-terephthalic acid, which contributes to its improved performance attributes, especially in terms of migration resistance and electrical properties. NINGBO INNO PHARMCHEM CO.,LTD. ensures the production of high-purity DOTP, typically presenting as a colorless or slightly colored, transparent liquid.

One of the primary advantages of using DOTP is its environmental consideration. With increasing regulatory scrutiny on phthalates globally, particularly in Europe and North America (e.g., REACH, RoHS directives), non-phthalate options like DOTP have gained significant traction. NINGBO INNO PHARMCHEM CO.,LTD.'s DOTP is free from EU-controlled o-phthalates, making it a safe choice for a wide range of consumer and industrial products, including sensitive applications where contact with humans or the environment is a concern.

Performance-wise, DOTP demonstrates parity or superiority to DINP in plasticizing efficiency and volatility. Crucially, it outperforms DOP in several critical areas. Products formulated with DOTP exhibit enhanced heat resistance, improved aging resistance, and greater durability. Its superior resistance to migration is vital in multi-layer applications or when the plasticized material is in contact with other surfaces, preventing plasticizer loss or staining. Furthermore, DOTP excels in providing excellent cold resistance and superior electrical properties, making it indispensable for applications such as electrical cables.

The versatility of DOTP is evident in its broad spectrum of applications. It is extensively used as a plasticizer for PVC soft products, ranging from films, sheets, and artificial leather to flooring and wall coverings. Its application in 70°C resistant cable materials is particularly noteworthy due to its favorable electrical insulation properties and thermal stability. Beyond PVC, DOTP shows excellent compatibility with various other polymers and resins, including acrylonitrile derivatives, polyvinylbutyral, nitrile rubber, and nitrocellulose. This compatibility extends its utility to synthetic rubber formulations, coating additives, lubricants for precision instruments, lubricant additives, and softeners for paper.

The typical quality parameters for high-grade DOTP supplied by NINGBO INNO PHARMCHEM CO.,LTD. include a low chroma number (indicating excellent clarity), high purity levels (above 99.5%), controlled density, very low acid value, minimal moisture content, a high flash point (typically above 210°C), and high volume resistivity. These specifications ensure product consistency, reliability, and safety in handling and application. NINGBO INNO PHARMCHEM CO.,LTD. adheres to stringent quality control measures throughout the manufacturing process to guarantee that every batch of DOTP meets the required standards, providing customers with a dependable and high-performing plasticizer.

Available in various packaging options to suit diverse customer needs, including 200kg drums, IBC tanks, or larger tanker loads, NINGBO INNO PHARMCHEM CO.,LTD. facilitates efficient transport and storage. Minimum order quantities are structured to support both smaller production needs and large-scale industrial applications, demonstrating flexibility in supply chain solutions.

In conclusion, Dioctyl Terephthalate (DOTP) stands out as a superior, environmentally conscious plasticizer, critical for enhancing the performance and safety of countless polymer-based products across diverse industries. Its robust properties and regulatory compliance make it an indispensable component for formulators worldwide.
