Exolit® OP 1260 (TP)

Phosphinate flame retardant system for polyester injection moulding applications

Edition Date :
December 03, 2013

Flame Retardant for Polyester Exolit OP 1260 (TP) is a non-halogenated flame retardant based on organic phosphinates. The product achieves its flame retardant effect through a combined gas phase and condensed phase mode of action. Exolit OP 1260 (TP) is based on commercially available chemical substances registered in inventories worldwide.

  • Applications

    Exolit OP 1260 (TP) was developed especially for use in polyester. It is especially suited for both glass-fiber reinforced and non-reinforced PBT. The flame retarded polyester compounds exhibit very good physical and electrical properties.

    Formulation
    In glass-fiber reinforced polyester, a dosage of about 18-20 % (by wt.) of Exolit OP 1260 (TP) is usually sufficient to obtain the UL 94 V-0 classification for electrical components (at 1.6 mm as well as 0.8 mm and 0.4 mm thickness). Subject to the polymer grade, processing conditions and glass-fibre reinforcement the dosage of the flame retardant may vary.
  • Processing

    Before incorporating Exolit OP 1260 (TP), it is important to pre-dry the polyester as usual. If possible, the resulting moisture content should be below 0.1 % (by wt.). Pre-drying of Exolit OP 1260 (TP) is not necessary. However, pre­drying (e.g. 4 h at 120 °C) is recommended, if even very low moisture contents must be avoided.
     
    The mixing and processing methods customary in powder processing of polymers can be used with Exolit OP 1260 (TP). The VDI Guideline 2263 Prevention of dust fires and dust explosions or the relevant national regulations must be observed.

    The optimum conditions for incorporating should be determined in each individual case. Care must be taken to ensure homogeneous dispersion of all components. The temperature of the polymer melt should not exceed 320 °C.
