        Orient IFR-P601


        Orient IFR-P601is a kind of halogen-free intumescent flame retardant (IFR) based on nitrogen and phosphorous retardant elements. It can be mixed with polypropylene resins easily and shows lower loading, higher stability and lower price as compared to other IFRs. The polypropylene resins containingOrient IFR-P601possess superior mechanical properties and do not release any dioxin and hydrogen halide, which can pass UL94V-0 rate during the flame retardant tests.

        Recommended dosage

        *Notes: The above recommended dosage is not a product quality guarantee. Different equipments, techniques ofproduction and prescriptions may lead to different loadings. Please refer to the actual parameters.





        Points for attention

        1)Orient IFR-P601 decomposed at 250℃under nitrogen atmosphere. To avoid slightly foaming, the temperature of twin screw should be controlled lower than230℃. In addition, it does not need screen mesh and should keep vacuum during the extruding process.

        2) Inorganic fillers such as CaCO3, Caron black, BaSO4and Mg(OH)2, will reduced the retardant properties.

        3)For PP resins with high melting index and products lower than 1.6 mm, these systems should be added anti-dripping agents to enhance the viscosity and to avoid melting dripping.

        4) The introduction of polypropylene wax can enhance the glabrous property of the retardant PP products, but the recommended loading is 0.5% and the maximum loading should be lower than 1%.

        5) When the loadings of Orient IFR-P601 in PP resins with low melt index are higher than 28%, the products with 1.6 mmthickness can pass the UL746 Ctest. For the high melt index PP resins, the products can also pass the UL746 Ctest with additional anti-dripping agents.

        Use and Storage

        Orient IFR-P601 products are packaged up by aluminoplastic bags with 25±0.2 kgin each one. The products should be stored in ventilating and drying warehouse and should be dried for 2-4 hours under 90-110℃after a long time preservation.
