Abstract
A flame retardant molding composition is disclosed. The composition that contains a polymeric component, preferably a polyamide, red phosphorus, zinc borate, talcum and a lanthanide compound, is characterized by its combined flame resistance and good mechanical properties. The composition may also contain fillers or reinforcing substances, an impact modifier and further conventional additives.
