 Exolit OP 1400 Terra was developed especially for use in polyamides. It is suited for polyamide 6 and 66 as well as polyphthalamides and other high temperature polyamides, e.g. PA 46, for both glass-fiber-reinforced and unreinforced grades. The flame retarded polyamide compounds exhibit very good physical and electrical properties. Flame retarded polyamides with Exolit OP 1400 Terra are suitable for applications also in hot and humid environment.

In glass-fiber-reinforced polyamide 6 or 6.6, a dosage of about 20 % (by wt.) of Exolit OP 1400 Terra is usually sufficient to obtain the UL 94 V-0 classification for electrical components (at 1.6 mm down to 0.4 mm thickness). In semi-aromatic polyamides the dosage can be reduced to approx. 15%. Subject to the polymer grade, processing conditions and glass- fibre reinforcement the dosage of the flame retardant may vary.

Before incorporating Exolit OP 1400 Terra, 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 1400 Terra 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 1400 Terra. 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.
