Description

Tri-m-Tolyl Phosphate is a high-purity organophosphate compound valued for its excellent performance as a flame retardant and plasticizer. This chemical is critical for enhancing the safety and durability of polymer materials by imparting flame resistance and improving flexibility. It is primarily sought after by manufacturers in the plastics, rubber, and specialty coatings industries for formulating products that require reliable fire safety standards.

Application

• As a flame retardant plasticizer in PVC (polyvinyl chloride) cables, films, and flooring.
• As a functional additive in engineering plastics and synthetic rubbers to improve flame resistance.
• As a lubricant additive to enhance extreme pressure properties and thermal stability.
• In the formulation of hydraulic fluids and fire-resistant hydraulic systems.
• As a viscosity modifier and processing aid in specialty polymer production.
• In the manufacture of adhesives and sealants requiring improved flexibility and fire retardancy.
