Product name: Triethyl Phosphate
English alias: TPP; Phosphoric acid triphenyl ester
CAS: 115-86-6
Molecular formula: C₁₈H₁₅O₄P
Appearance: White crystalline flakes or powder
Package: 5kg/bag
TPP is a versatile organophosphorus compound that serves primarily as a flame retardant and plasticizer in a wide range of industrial applications. It is known for its excellent flame-retardant properties, high efficiency, and compatibility with various polymers. This product appears as white crystalline flakes or powder and is characterized by its chemical stability and low volatility. As an effective flame retardant, Triphenyl Phosphate works by promoting char formation and inhibiting the combustion process.

1.Flame Retardant: Primarily used as a flame retardant in engineering plastics such as modified PPO, PC/ABS alloys, polycarbonate, and phenolic resins to significantly improve fire resistance.
2.Plasticizer: Functions as an efficient plasticizer for cellulose acetate, nitrocellulose, and other polymers to enhance flexibility and processability.
3.Hydraulic Fluid Additive: Triethyl Phosphate used as an additive in hydraulic fluids and lubricants for its anti-wear and flame-retardant properties.
4.Adhesive & Coating Industry: Triethyl Phosphate employed as a flame retardant additive in adhesives, varnishes, and coatings to meet safety standards.
5.Rubber Industry: Triethyl Phosphate acts as a flame retardant and plasticizer in various rubber products.
Triethyl Phosphate is generally considered to have low acute toxicity. However, it may cause irritation to the skin, eyes, and respiratory system. Proper personal protective equipment (PPE) such as gloves and goggles is recommended during handling. It is not classified as a carcinogen, but prolonged exposure should be avoided. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
Store in a cool, dry, and well-ventilated area.
Keep the container tightly closed to prevent contamination and moisture absorption.
Avoid contact with strong oxidizing agents.
Keep away from heat, sparks, and open flames.
Triphenyl Phosphate is typically supplied in:
25 kg woven bags with inner plastic liner.
500 kg or 1000 kg palletized bags (optional).
Also available in 25 kg cardboard drums upon request.
All packaging complies with standard transport regulations for industrial chemicals
