  • Flame retardant polyamides
    Patent number: 5618864
    Abstract: Flame retardant polyamide compositions are provided which contain melamine as the flame retardant. Flame retardant benefits are particularly realized by a composition which is a blend of melamine with a copolymer of polyamide-6.6 and 6. Use of heat stabilizers in the preferred compositions minimizes the thermal aging properties of the copolymer compared to polyamide-6.6.
