Triphenyl Phosphate (TPP)

Product Overview

Triphenyl Phosphate (TPP), with CAS number 115-86-6, is a high-performance organophosphorus compound extensively utilized in the polymer and plastics industry. As a colorless to white flaky crystalline solid, it offers excellent thermal stability, low volatility, and compatibility with a broad range of organic matrices. Our industrial-grade TPP meets stringent quality standards with an assay of ≥99%, ensuring consistent performance in demanding applications.

Specifications

Industrial Applications

Triphenyl Phosphate serves dual functionality as both a flame retardant and a plasticizer, making it indispensable in modern polymer compounding. Key application areas include:

• Cellulose-based resins (e.g., cellulose acetate and nitrocellulose) for improved flexibility and fire resistance.
• Vinyl resins such as PVC, where it enhances processability and reduces flammability without compromising clarity.
• Natural and synthetic rubber formulations, acting as a secondary plasticizer and stabilizer.
• Engineering thermoplastics and adhesives requiring UL-certified flame retardancy.

As a non-halogenated flame retardant, TPP aligns with global environmental and safety regulations, offering a sustainable alternative to brominated compounds. Its low migration rate ensures long-term performance in end-use products.

Quality & Supply Assurance

Manufactured under ISO-certified processes, our TPP is packed in 25 kg composite paper bags lined with black polyethylene inner liners to prevent moisture ingress and light degradation. With an annual production capacity of 8,000 metric tons across phosphate-based flame retardants, plasticizers, and stabilizers, we guarantee reliable global supply and technical support for industrial customers.
