🔥 ADP Flame Retardant: Helping Glass-Fiber-Reinforced PA6 Achieve “Strong Yet Flame-Resistant”
For glass-fiber-reinforced PA6, achieving both high mechanical strength and excellent flame retardancy is not easy.
Glass fibers improve strength—but can also create the well-known “wick effect”, making flame retardancy more challenging. Meanwhile, excessive flame-retardant loading may negatively affect mechanical properties.
💡 This is where ADP comes in.
ADP (Aluminum Diethylphosphinate) is a highly efficient phosphorus-based flame retardant widely used in engineering plastics and flame-retardant polymer systems.
When combined with MPP (Melamine Polyphosphate), ADP can generate a strong synergistic flame-retardant effect through both the gas phase and condensed phase.
🔬 Why ADP + MPP?
✔ Efficient flame inhibition – ADP contributes to gas-phase flame inhibition by interfering with combustion chain reactions.
✔ Protective char formation – In combination with MPP, the system promotes the formation of a protective char layer, helping isolate heat and oxygen.
✔ Reduced flame-retardant loading – Synergistic action can help achieve the required flame-retardant performance with a more efficient additive package.
✔ Better mechanical-property retention – Lower total additive loading can help reduce the negative impact on the PA6 matrix and glass-fiber/matrix interface.
✔ Suitable for engineering plastics – Particularly attractive for flame-retardant PA6/GF and other high-performance polymer systems.
📌 Typical Applications
• Glass-Fiber-Reinforced PA6
• PA6 / PA66 Engineering Plastics
• Flame-Retardant Compounds
• Electrical & Electronic Components
• Automotive Components
• Industrial Plastics
• Connectors, Housings & Structural Parts
For applications where flame retardancy, mechanical strength and durability need to be balanced, ADP-based synergistic systems are worth exploring.
