Halogen-free, flame resistant and hydrolysis resistant polymer compositions are disclosed. The polymer composition of the present disclosure is also formulated to have improved electrical tracking resistance. 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 optionally in combination with a phosphite and/or a nitrogen-containing synergist. In order to improve electrical tracking resistance, one or more electrical resistance agents are added to the polymer composition. The electrical resistance agent, for instance, can be a flexible polymer.
