Application:
Mflam 1439 is a halogen-free intumescent flame retardant designed by our company for polyolefin. It uses phosphorus and nitrogen as the main flame retardant elements (the system does not contain APP). It mainly plays a flame retardant role by charring and intumescent flame retardant mechanism. It is fully compliant with RoHS and REACH regulations. The biggest feature of this product is its better precipitation resistance and good processability. It also has the characteristics of high flame retardancy, water resistance, light aging resistance, low smoke and non-toxicity. PP treated with Mflam 1439 can reach UL 94 V-0 level, suitable for 5VA system.
