Abstract
Halogen-free, flame resistant polymer compositions are disclosed. The polymer composition contains a thermoplastic polymer, such as polybutylene terephthalate. The thermoplastic polymer is combined with a flame retardant that includes a phosphinate, a phosphite, and a nitrogen-containing synergist. In addition, the composition can contain a fluoropolymer and an organometallic compatibilizer. The flame resistant composition displays excellent flame resistance even when containing the thermoplastic polymer in amounts greater than 60% by weight.
