Tris (2-chloroethyl) phosphate, also known as flame retardant TCEP, Niax Flame Retardant 3CF, Genomoll P, Celluflex CEF, Antiblaze 100, Fyrol CEF, is an additive type phosphate flame retardant and plasticizer. Tris (2-chloroethyl) phosphate has excellent flame resistance, excellent low temperature resistance and UV resistance. Its vapor can only be ignited with an open flame above 225 ℃ to burn, but it will be self-extinguished immediately after removing the fire source. Using tris (2-chloroethyl) phosphate as a flame retardant can not only improve the material level of products, but also improve the water resistance, acid resistance, weather resistance, cold resistance and antistatic properties. Tris (2-chloroethyl) phosphate is commonly used in flame retardant paints based on nitro and acetate fibers. It is also used in unsaturated polyester, ethyl cellulose, soft and rigid polyurethane, acrylic resin, polyvinyl acetate, phenolic resins, etc. Tris (2-chloroethyl) phosphate can also be used as plasticized flame retardants for soft polyvinyl chloride, an extractant for rare metals, an additive for lubricating oil and gasoline, a modifier for polyimide processing, a coolant for magnesium metal, and it is especially suitable for flame retardant transportation belts in coal mines, flame-retardant polyethylene cables and wallpapers, flame retardant treatment of polyacrylonitrile fiber, cardboard, wood, and petroleum additives.

Practical application

Flame retardant TCEP can be used in the production of flexible and rigid polyurethane foams. However, it is more effective for rigid polyurethane foam, which can make its flame retardant index (LOI) reach 26. This is because rigid polyurethane foam has a high closed cell ratio, low air permeability, flame retardant TCEP is difficult to volatilize, and the flame retardant effect is maintained for a long time. The disadvantage is that the amount is large. If the amount exceeds 15%, the physical properties of rigid polyurethane foam will decrease. When flame retardant TCEP is used in soft polyurethane foam, such as flame retardant modified high rebound foam, it can be used in combination with melamine. Flame retardant TCEP can be directly injected into the mixing head during the foaming process alone, or it can be mixed with the polyether polyol before foaming, while reducing the viscosity of the polyol component.

Recommended dosage

In unsaturated polyesters, the amount of flame retardant TCEP is 10% to 20%. In rigid polyurethane foam (using flame retardant polyethers as raw materials), the amount of flame retardant TCEP is about 10%. When used as an auxiliary plasticizing flame retardant in high-quality polyvinyl chloride, the amount of flame retardant TCEP is 5% to 10%.
