Flame Retardant for Plastics FAQ
What makes our Flame Retardant for Plastics environmentally friendly?
Our halogen-free formula contains no brominated or chlorinated compounds, making it RoHS, REACH, and WEEE compliant. The phosphorus-nitrogen system provides excellent flame retardancy without generating toxic fumes during combustion. Unlike traditional halogenated retardants, our product doesn't contribute to dioxin formation when exposed to fire.
How does Flame Retardant for Plastics affect mechanical properties?
Our specially formulated additive maintains over 90% of the host polymer's mechanical strength. The optimized particle size distribution ensures excellent dispersion without causing stress concentration points. Impact modifiers in our formulation compensate for any potential brittleness, resulting in balanced mechanical performance.
What processing methods are suitable for Flame Retardant for Plastics?
This additive is compatible with all standard plastic processing techniques including injection molding, extrusion, blow molding, and compression molding. For best results, we recommend pre-drying at 80°C for 2-4 hours before processing. The product's thermal stability allows processing within typical temperature ranges for each polymer type without degradation.
