glass - fibre - reinforced electrical properties Phosphorus - based Flame Retardant for polyamides

Name: Diethylphosphinic acid aluminum salt

CAS No.: 225789-38-8

Use:glass - fibre - reinforced and unreinforced grades

non - halogenated Flame Retardant Halogen Free Based Organic Phosphonates


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.
