A process a process of forming a non-halogenated flame retardant (FR) hindered amine light stabilizer (HALS) cross-linker is disclosed. The process includes forming a mixture that includes a first molecule having a hindered amine group. The first molecule corresponds to a functionalized 2,2,6,6-tetramethylpiperidine (TMP) molecule. The process also includes forming the non-halogenated FR HALS cross-linker via a chemical reaction of the first molecule a second molecule. The second molecule includes a phosphoryl group, a chloride group, and at least one cross-linkable (CL) moiety.
