Exolit® OP 1312

Exolit® OP 1312

Exolit OP 1312 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 1312 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 1312 is a white powder.

Applications & Uses

Processing

Before incorporating Exolit OP 1312, 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 1312 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 1312. 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.

Applications

Exolit OP 1312 was developed especially for use in polyamides. It is suited for both glass-fibre-reinforced and unreinforced grades. The flame retarded polyamide compounds exhibit very good physical and electrical properties. Exolit OP 1312 is also used in TPU for cable extrusion but also various injection moulded parts and artificial leather.

Formulation 
In glass-fibre-reinforced polyamide 6 or 6.6, a dosage of 15 to 20 % (by wt.) Exolit OP 1312 is usually sufficient to obtain the UL 94 V-0 classification for electrical components (at 1.6 as well as 0.8 mm thickness). Subject to the polymer grade, processing conditions and glass- fibre reinforcement the dosage of the flame retardant may vary.
