Abstract

The invention relates to a halogen free flame retardant polyester composition suitable for use as a molding composition for making lampholders, comprising (A) a polymeric material consisting for at least 50 wt. %, relative to the total weight of the polymeric material, of a thermoplastic polyester; (B) a flame retardant system in an amount of 11-35 wt. %, relative to the total weight of (A), (B) and (C), and consists of: melamine cyanurate, and optionally one or more of the following flame retardant components: another phosphorus-free nitrogen based organic flame retardant compound, a phosphorus containing flame retardant excluding elementary phosphorus, in an amount of less than 1 wt. %, relative to the total weight of (A), (B) and (C); an inorganic flame retardant synergist, and an organic flame retardant synergist (C) a fibrous reinforcing agent in an amount of 5-35 wt. %, relative to the total weight of (A), (B) and (C); and (D) a mould release agent in an amount of at least 0.01 wt. %, relative to the total weight of (A), (B) and (C).
