Isopropylated Triphenyl Phosphate (IPPP / Reofos 65)
Isopropylated triphenyl phosphate (IPPP) is a liquid aryl phosphate ester flame retardant and plasticizer used in flexible PVC, polyurethane foams, and rubber. Its isopropyl-substituted aryl structure delivers improved thermal stability, hydrolytic stability, and lower volatility compared to unsubstituted triphenyl phosphate, while retaining comparable phosphorus content and FR effectiveness. IPPP is widely used in flexible PVC wire and cable jacketing, PU foam, and vinyl coatings where both plasticization and flame retardancy are needed in a single additive.

مميزات المنتج
- Improved hydrolytic stability over unsubstituted triphenyl phosphate reduces long-term migration from PVC
- Liquid form enables easy incorporation into PVC plastisols, polyurethane polyol blends, and rubber
- Dual plasticizer-FR function replaces two separate additives, reducing formulation complexity and cost
- Low color (water-white) preserves optical clarity in transparent films and light-colored PVC compounds
