What principles should be followed when selecting flame retardants for nylon?

In the process of manufacturing flame-retardant nylon, the selection of flame retardants mainly considers factors such as flame-retardant efficiency, product performance, and toxicity. For example, one should consider the requirements for the flame-retardant grade of the product, the mechanical properties of the material, surface characteristics, processing performance, and colorability. After determining the type and amount of flame retardant based on usage requirements, the selection of flame retardant additives and process conditions is crucial. The following principles should be adhered to:

1. Good flame-retardant effect with minimal usage, and good compatibility with nylon;

2. High decomposition temperature, resistant to decomposition at nylon processing temperatures;

3. Excellent durability with no significant surface migration;

4. Minimal impact on the mechanical and electrical properties of the material, and minimal corrosion to equipment;

5. Non-toxic, non-harmful, environmentally friendly, and cost-effective.
