Description
Fyrol FR 2, also known as Tris(1,3-dichloro-2-propyl) Phosphate, is a halogenated phosphorus flame retardant that is widely used in various industries due to its effectiveness in enhancing fire safety. It is a clear, colorless, viscous liquid that is generally a super-cooled liquid at room temperature but may occasionally solidify when held at low temperatures for prolonged periods. Fyrol FR 2 has a relatively low molecular weight, low water solubility, and low lipophilicity.
Uses
Used in Polyurethane Foams:
Fyrol FR 2 is used as a flame retardant for flexible polyurethane foams (PUFs) to improve their fire resistance and safety. This application is particularly important in industries such as furniture manufacturing, automotive seating, and bedding products.
Used in Automotive Industry:
Fyrol FR 2 is used as a component in molded automotive seating foam, including seat cushions and headrests, to enhance fire safety and meet regulatory standards.
Used in Furniture and Related Products:
Fyrol FR 2 is used as a flame retardant in slabstock foam used in furniture manufacturing, providing an additional layer of safety and protection against fire hazards.
Used in Building and Construction Materials:
Fyrol FR 2 is used in the production of building and construction materials to improve their fire resistance and meet safety regulations.
Used in Fabrics, Textiles, and Leather Products:
Fyrol FR 2 is used as a flame retardant in the manufacturing of fabrics, textiles, and leather products to enhance their fire safety and protect users from potential fire hazards.
Used in Paints and Coatings:
Fyrol FR 2 is used as an additive in the production of paints and coatings to improve their fire resistance and provide additional safety benefits.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Fyrol FR 2 hydrolyzes slowly when refluxed with an aqueous acid. Under alkaline conditions, Fyrol FR 2 exhibits a slow cleavage. Fyrol FR 2 has plasticizing properties and, as such, may soften or deteriorate certain plastics and elastomers (particularly vinyl-based resin, neoprene and natural rubbers).
Fire Hazard
Fyrol FR 2 is combustible.
Safety Profile
Moderately toxic by
ingestion. An experimental teratogen. Experimental reproductive effects.
Questionable carcinogen with experimental
carcinogenic data. Mutation data reported.
When heated to decomposition it emits
toxic fumes of Cland POx.
Environmental Fate
A series of studies have been performed to evaluate the environmental fate and bioaccumulation potential of Tris(1,3-dichloro-2-propyl)phosphate (TDCPP).EU concluded that TDCPP is expected to be persistent in water, sediment, sewage sludge, and soil. When emitted to the environment, the EU concluded that TDCPP will likely adsorb to particulate matter, based on its low volatility and relatively high adsorption coefficient. The Henry’s law constant suggests that TDCPP will preferentially partition to water, rather than air. When assessing TDCPP's potential for persistence or bioaccumulation, the EU determined that TDCPP can potentially be persistent or very persistent and that it does not meet the criteria for bioaccumulative or very bioaccumulative compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 13674-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,7 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13674-87:
(7*1)+(6*3)+(5*6)+(4*7)+(3*4)+(2*8)+(1*7)=118
118 % 10 = 8
So 13674-87-8 is a valid CAS Registry Number.
