Description

Tri-p-Tolyl Phosphate is a high-purity organophosphate ester valued for its excellent performance as a flame retardant and plasticizer. This compound is critical for enhancing the safety and durability of polymer materials by imparting flame resistance and flexibility. It is primarily needed by manufacturers in the plastics, rubber, and specialty chemical industries for producing high-performance materials.

Application

• Primary use as a flame retardant plasticizer in polyvinyl chloride (PVC) and other polymer systems.
• Component in hydraulic fluids and lubricant additives for industrial machinery.
• Used as a solvent and extractant in various chemical synthesis and purification processes.
• Employed in the formulation of fire-resistant coatings and sealants.
• Acts as a viscosity modifier and anti-wear agent in specialty lubricants.
• Potential use as an intermediate in the synthesis of other organophosphorus compounds.
