N-P Intumescent Flame Retardant for PP (FR-PP NP) Product description： This product, mainly contained Nitrogen and Phosphorus, is a kind of halogen-free flame retardant for polyolefin, especially for PP. Otherwise, the modified PP can pass glow-wire test and GWIT 750℃&GWFI 960℃. Moreover, it is free from the restrictions of ROHS Directive 2002/95/EC approved by the EU and the Council. No anti-dripping agent. Benefits： 1. Low dosage.（20-25% can reach UL94 V-0 3.0mm；35% can reach UL94 5VA）. 2. Halogen-free & environment-friendly. 3. When extrusion with PP, no water-sliding, with good water-resistance. 4. FR with PP can pass GWIT 750℃.

We suggest the processing temperature should below 250℃to avoid FR`s slight decomposition. 2. Keeping a certain vacuum degree when processing in double-screw extruder. 3. Fillers (such as CaCO3、Talc、BaSO4)can affect the flame retardant performance. 4. Glass Fiber can use in the system, but affect product`s color. 5. Carbon black is also applied for the system, but the dosage should below 0.5%. Packaging and Handling: 25kgs/bags with PE inner，handle with care, cold storage. In ventilated and dry condition.
