Halogen-Free Flame Retardant Thermoplastic Polyesters with Enhanced Processability

摘要

Many phosphorus containing additives and nitrogen synergists are available for use as flame retardant systems in engineering plastics, to develop halogen-free products for the electrical & electronics industry. However, many issues such as blooming, mold deposits, short-shots, and tool corrosion are associated with the use of such additives in polyesters. We illustrate typical issues encountered with the use of halogen-free systems in PBT and demonstrate how the Celanex~? XFR~? series from Ticona overcomes those issues and can be used as a viable alternate to halogenated compounds. We also highlight the unique advantages of our halogen-free PBT products over conventional halogenated PBT products.
