PhosflexTM 390 is isodecyl diphenyl phosphate made from synthetic feedstocks. It is a highly efficient plasticizer for PVC, with very good low temperature flexibility, and excellent solvating properties for fast fusion. One of the unique characteristics of PhosflexTM 390 is its ability to reduce flammability while also reducing smoke. Typically when flame retardants are used, the combustion efficiency of the compound is decreased and as a result, smoke (incomplete combustion particles and gases) increase.

PhosflexTM 390 does both exceeding well in many types of polymer systems, especially flexible vinyl and vinyl alloys. PhosflexTM 390 has excellent compatibility in PVC and other plastics.

Formulated correctly, this product performs well in vinyl composites for outdoor applications where exposure to UV irradiation and weathering is critical. PhosflexTM 390 has been found useful in FR foamed vinyl and vinyl alloys (PVC/nitrile rubber), calendared sheet goods, vinyl wire and cable and outdoor PVC applications. In certain elastomers, Phosflex® 390 can be useful as a solvator to improve the tactile feel of the rubber composites.
