Flame Retardant Nylon

Commonly known as nylon polyamide (PA), is the molecular main chain containing repeated amide groups (-NHCO-) general thermoplastic resins. Nylon for good mechanical properties, electrical properties, heat resistance, toughness, oil resistance, wear resistance, self lubrication, chemical resistance and other excellent performance, widely used in various fields. Without modification of the flame retardant nylon poor combustion can only reach its vertical UL94 V-2, and oxygen index of 24 or so, and dropping generated during combustion, are flammable materials, use of the process extremely fires. Particularly in the electronics field, due to a fire caused numerous nylon, resulting in greater losses, therefore, become modified flame retardant nylon academia and industry and the research topics of common concern. Nylon in the wider application of The halogen-free flame retardant red phosphorus and melamine salts. Red phosphorus flame retardant with high efficiency and can improve the product arc resistance, but the color of their storage and the limitations greatly limit its application in Nylon, generally used of nylon 6. The other is the use of halogen-free flame retardant nylon melamine salt is mainly melamine salt of uric acid and phosphate. They have good flame-retardant efficiency, but poor thermal stability, and make products as easy to absorb moisture and humid conditions in poor electrical properties
