ProFlex DROP is a low-viscosity phosphate ester plasticizer with commendable gelling behavior in flexible PVC. Its versatility extends to functioning as a flame retardant in materials such as TPU (thermoplastic polyurethane), NBR (nitrile butadiene rubber), and cellulose acetate. Particularly recommended for applications where fire risk reduction is a priority, ProFlex DROP appears as a clear or light yellow transparent liquid. Its multifunctional properties make it a valuable choice for enhancing both the flexibility of PVC and the flame retardancy of various materials.
