Exolit® OP 1311

Exolit® OP 1311 is a non-halogenated flame retardant based on organic phosphinates. The product achieves its flame retardant effect through intumescence. The thermoplastic polymer with Exolit® OP 1311 foams and crosslinks on exposure to flame and forms a stable char at the surface acting as a barrier. The protective layer provides a heat- insulating effect, reduces oxygen access and prevents dripping of molten polymer. Exolit® OP 1311 is a white powder.

Applications & Uses

Product Applications
  • Application:
  • Exolit® OP 1311 was developed especially for use in polyamides. It is suited for both glass-fiber-reinforced and unreinforced grades. The flame retarded polyamide compounds exhibit very good physical and electrical properties.
  • Formulation
  • In glass-fiber-reinforced polyamide 6, a dosage of 15 to 20 % (by wt.) Exolit® OP 1311 is usually sufficient to obtain the UL 94 V-0 classification for electrical components (at 1.6 as well as 0.8 mm thickness). For polyamide 66 applications, we recommend Exolit® OP 1312. Subject to the polymer grade, processing conditions and glass- fibre reinforcement the dosage of the flame retardant may vary.
Processing Parameters
  • Before incorporating Exolit OP 1311, it is important to predry the polyamide as usual.
  • If possible, the resulting moisture content should be below 0.1 % (by wt.).
  • Predrying of Exolit OP 1311 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 1311.
  • 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 300°C.
