Atrajet™ 400 P
Atrajet 400 P 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. The thermoplastic polymer with Atrajet 400 P forms on exposure to flame 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. Atrajet 400 P is a white powder.

Atrajet 400 P was developed especially for use in polyamides. It is suited for both glass-fibre-reinforced and unreinforced grades and for PA 6, PA 66 and for high temperature polyamides. The flame retarded polyamide compounds exhibit very good physical and electrical properties.
Atrajet 400 P shows beginning weight loss above 200°C (TGA, approx. 3%). For a better thermal stability, we rerommend Exolit OP 1400.
In glass-fibre-reinforced polyamide 6 or 6.6, a dosage of about 20 % (by wt.) Atrajet 400 P is usually sufficient to obtain the UL 94 V-0 classification for electrical components (at 1.6 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.
Before incorporating Atrajet 400 P, it is important to predry the polyamide as usual. If possible, the resulting moisture content should be below 0.1 % (by wt.). Predrying of Atrajet 400 P 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 Atrajet 400 P. 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 340 °C.
