For B2B buyers and technical professionals in the chemical and manufacturing sectors, a deep understanding of the raw materials they procure is fundamental. Tricresyl Phosphate (TCP), a significant organophosphate ester, is one such compound whose properties and manufacturing process warrant close attention. As a NINGBO INNO PHARMCHEM CO.,LTD. enterprise, we are committed to providing not just the product, but also the technical insights that empower our clients to make informed decisions. This article explores the science behind TCP, its key properties, and the manufacturing considerations relevant to industrial procurement.

Tricresyl Phosphate, with the CAS number 1330-78-5, is chemically characterized as a mixture of isomeric esters derived from cresol and phosphoric acid. Its molecular formula is C21H21O4P, and it typically presents as a clear, colorless to slightly yellow, viscous liquid with a faint aromatic odor. A critical specification for TCP is its flash point, which is generally high (around 225°C), indicating its relative stability and safety in handling compared to more volatile compounds. Its low acid value and minimal free phenol content are indicative of high purity, which is crucial for consistent performance as both a flame retardant and a plasticizer. These properties collectively contribute to its widespread use in industries requiring enhanced material safety and flexibility.

The synthesis of TCP typically involves the reaction of cresol isomers with phosphorus oxychloride or phosphoric acid. While the fundamental chemistry is well-established, modern manufacturing processes, such as those employed by NINGBO INNO PHARMCHEM CO.,LTD., focus on optimizing reaction conditions, purification techniques, and waste minimization to ensure high product purity, environmental responsibility, and cost-effectiveness. Achieving a low ortho-isomer content is particularly important, as certain isomers have been associated with higher toxicity. Our manufacturing process is designed to yield a product that balances performance with safety, meeting international standards.

From a B2B perspective, understanding these manufacturing nuances is vital when you consider where to buy TCP. Sourcing from a manufacturer that prioritizes quality control, process efficiency, and regulatory compliance ensures that you receive a product that will perform reliably in your applications, whether it’s for enhancing the flame retardancy of PVC, acting as an anti-wear additive in lubricants, or improving the dielectric properties of cable insulation. Engaging with a knowledgeable TCP supplier like us allows for a more informed purchase, backed by technical expertise and a commitment to delivering value. We are ready to discuss your specific requirements and provide tailored solutions.
