UV stabilization of polypropylene fiber containing brominated flame retardants has been the focus of intense technical efforts with only limited success. Acid generated by the flame retardants deactivates HALS, thus severely reducing the HALS' effectiveness. Because of this interaction, flame retarded polypropylene fiber has been generally restricted to applications requiring little or no UV stability. Evaluation of structure‐performance characteristics of both flame retardants and stabilizers allow development of packages which optimize processability, flame retardancy, and UV stability. This paper reviews progress in the stabilization of flame retarded PP fiber and presents new advances in this field.
