The MH-4801 halogen-free flame retardant masterbatch for PP is an environmentally friendly flame retardant system containing phosphorus and nitrogen. Based on MH-FR/PP-1 product, development of non-precipitation intumescent halogen-free flame retardant masterbatch for PP can meet different application requirements of customers.
In comparison with FR powder, our halogen-free flame retardant masterbatch features convenient processing, easy dispersion, and strong compatibility with matrix resin. This fire retardant system is especially suitable for use in various PP materials or other polyolefin.
Proper addition of our product allows PP to reach flammability rating UL94-V0 (1.5mm). Additionally, the halogen-free flame retardant masterbatch has passed both RoHS certification and 850℃ hot glow-wire test. Other prominent characteristics include low smoke amount, ultra high cost-performance ratio, and low corrosion to moulds, etc.
Advantages
1. High Processing Temperature
Our product can offer processing temperature of above 270 degrees Celsius to meet the requirements of various polymers, especially polypropylene.
2. Good Compatibility
The intumescent halogen-free flame retardant masterbatch is well compatible with PP, PE, and EVA. Therefore, the end product is also provided with superb mechanical properties.
3. Strong Ageing Resistance
Our product can be recycled and re-processed. It fully satisfies environmental requirements.

Note
1. Adjustable Extrusion Process
Firstly, the twin-screw processing temperature should not be too high, or else mild foaming will occur resulted from a small amount of flame retardant decomposition.
Secondly, a filter should not be added during extrusion process, otherwise foaming will occur easily.
Thirdly, please maintain a certain degree of vacuum in the extrusion process to make extruded materials stable.
2. Based on different requirements of final products, please choose a suitable resin to make both extrusion processing and injection molding processes much easier.
3. A formulation system can not be added with substances which may cause flame-retardancy failure. When the dosage of carbon black is higher than 0.5%, the halogen-free flame retardant masterbatch will cease to be effective. Additionally, the fire retardant may be affected by inorganic padding materials such as fiber glass, calcium carbonate, talc, barium sulfate, etc.
Packing, Storage and Transportation
