Halogen-free, flame resistant and hydrolysis 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 can include a phosphinate, a phosphite, and a nitrogen-containing synergist. In addition, the composition can contain various hydrolysis resistant components. For instance, the polyester polymer incorporated into the composition can have a relatively low amount of carboxyl end groups. In addition, the composition can contain reinforcing fibers that are coated with a hydrolysis resistant agent. The composition can also contain an organometallic compatibilizer. |
