Diethylphosphinic acid aluminum salt is a non-halogenated flame
retardant based on organic phosphinates. The product achieves its
flame retardant effect through intumescence. The thermoplastic
polymer with Diethylphosphinic acid aluminum salt 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.
Diethylphosphinic acid aluminum salt 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.
In glass-fibre-reinforced polyamide 6 or 6.6, a dosage of 15 to 20
% ( by wt ) Diethylphosphinic acid aluminum salt 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 - fiber reinforcement the dosage of
the flame retardant may vary.
