Triethyl Phosphate (TEP) | CAS 78-40-0 | Flame Retardant & Industrial Solvent
Overview
Triethyl Phosphate (TEP) is a colorless, transparent, and high-boiling liquid with a mild, fruity odor. It is highly soluble in water and completely miscible with most organic solvents. Due to its unique chemical properties, TEP serves a dual purpose in the chemical industry: it is both a highly efficient, halogen-free phosphorus flame retardant and a powerful, versatile industrial solvent.

Key Applications
- Flame Retardant: Acts as a highly effective, halogen-free flame retardant for polyurethanes (PU foams), unsaturated polyester resins, and phenolic resins, providing excellent fire resistance while maintaining material integrity.
- Industrial Solvent & Plasticizer: Serves as a strong solvent and plasticizer for cellulose acetate, nitrocellulose, and various synthetic resins. It is widely used in the production of specialized coatings, paints, and adhesives.
- Chemical Intermediate: A critical intermediate and alkylating agent in the synthesis of pharmaceuticals and agricultural chemicals (such as pesticides and insecticides).
- Catalyst: Utilized as a catalyst in the production of acetic anhydride and other fine chemical syntheses.
Packaging & Storage
We provide durable, moisture-proof packaging tailored for liquid bulk export.
- 200 KG / 220 KG Galvanized Iron Drum or HDPE Drum
- 1000 KG / 1100 KG IBC Tote
- 20 - 24 MT ISO Tank for bulk liquid transport
Storage Conditions: Store in a cool, dry, and well-ventilated indoor warehouse. Keep containers tightly sealed to prevent moisture absorption, as TEP is hygroscopic. Store away from strong oxidizing agents and strong alkalis.
🛡️ Safety & Transport Information
- Transport Classification: Not classified as dangerous goods for transport (UN Number: N/A). Safe for general cargo shipping via sea, air, and land.
- Handling Precautions: TEP is generally safe to handle but can cause mild irritation to the eyes, skin, and respiratory tract if direct contact occurs. It is combustible at high temperatures (Flash Point ~115°C). Operators should wear basic PPE including safety goggles and gloves. Ensure adequate ventilation in the workplace.
