Exolit OP 1400 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 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 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). 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.
