Product Description

Wholesale High Quality Halogen Free Flame Retardant Melamine Polyphosphate Mpp

Wholesale High Quality Halogen Free Flame Retardan


      Melamine Polyphosphate (MPP) is a halogen-free flame retardant with a wide range of application. MPP of Copolyforce is a type of high-efficiency nitrogen-phosphorus intumescent flame retardant manufactured by special blocking process. It has very high thermal stability and decomposition temperature of 1% thermal weight loss ≥360℃.The product also has the advantages of low water solubility and excellent flame retardant performance, which is mainly used for flame retardant of glass fiber reinforced nylon, polyurethane and fiber fabrics, etc.

Processing Recommendations:

(1)Because decomposition temperature of MPP in air is above 360 ℃, the processing temperature of twin screw extruder can be adjusted higher in accordance with the actual need to enhance the dispersion and enhance the plasticization effect. Maintain vacuum of the twin screw extruder during the processing is also needed. Application Examples Machine:Twin screw Extruder 35 Machine Temperatures Set(℃):240-270 Machine Rotate Speed:240-360rpm Recommended Screw Combination: Extruder 35(Total thread block: 46,screw length: 1428mm)
