Exolit™ OP 1380
Exolit OP 1380 is a non-halogenated flame retardant based on organic phosphinates for reinforced polyamide 66 and polyamide 6. The product achieves its flame retardant effect through a combined gas phase and condensed phase mode of action. Compared to Exolit OP 1312, Exolit OP 1380 gives an improved performance in the glow wire ignition temperature (GWIT according to IEC 60695). Exolit OP 1380 is based on a new chemical substance which is currently being registered in various national and regional chemical inventories.

Exolit OP 1380 was developed especially for use in polyamides. It is suited for polyamide 6 and 66 for both glass-fiber-reinforced and unreinforced grades. The flame retarded polyamide compounds exhibit very good physical and electrical properties.
In glass-fiber-reinforced polyamide 6 or 6.6, a dosage of about 20 % (by wt.) of Exolit OP 1380 is usually sufficient to obtain GWIT of 775°C the UL 94 V-0 classification for electrical components (at 1.6 mm as well as 0.8 mm and 0.4 mm thickness). To achieve GWIT higher than 775°C we recommend increasing the dosage to about 23%. Subject to the polymer grade, processing conditions and glass-fiber-reinforcement the dosage of the flame retardant may vary.
Before incorporating Exolit OP 1380, it is important to pre-dry the polyamide as usual. If possible, the resulting moisture content should be below 0.1 % (by wt.). Pre-drying of Exolit OP 1380 is not necessary. However, pre-drying (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 1380. 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.
