Introduction
As an upgrade product based onOrient IFR-P601,Orient IFR-P602contains high efficient assistant agents and is produced by special process. As compared toOrient IFR-P601, it possesses better waterproof property.The polypropylene resins containingOrient IFR-P602present low density, low smoke release, low corrosiveness for molds and high cost performance.

*Notes: The above recommended dosage is not a product quality guarantee. Different equipments, techniques of production and prescriptions may lead to different loadings. Please refer to the actual parameters.
Application
Points for attention
1)Orient IFR-P602 decomposed at 260℃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 highest loading should be lower than 1%.
5) When the loadings of Orient IFR-P602 in PP resins with low melt index are 25%~30%, the products with1.6 mmthickness can pass the UL746 Ctest. For the high melt index PP resins, the products can also pass the UL746Ctest with additional anti-dripping agents.
Use and Storage
Orient IFR-P602 products are packaged up by aluminoplastic bags with25±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.
