It boasts a high autoignition temperature above 400C, low vapor pressure, and a flash point greater than 200C, which contributes to its utility as a flame retardant. Its chemical stability under recommended conditions provides a long shelf life of up to 2 years.
Applications and UsageWidely utilized as a flame retardant in polymers, plastics, textiles, and rubbers, Tris(2-chloroethyl) phosphate imparts significant fire-resistant properties to finished goods. Its effectiveness comes from both its chemical structure and ability to blend uniformly in applied mediums. Its additional plasticizing capability enhances material flexibility.
Safe Handling and StorageDue to its toxic nature and environmental impact (notably as an aquatic toxicant), Tris(2-chloroethyl) phosphate should be stored in tightly sealed containers, in dry, well-ventilated areas. Transport and packaging comply with international standards (Class 6.1, UN 2588) for toxic chemicals, making it suitable for distribution, export, and retail under regulated conditions.
FAQs of Tris(2-chloroethyl) phosphate:
