Aluminum diethyl phosphhinate

  (CAS: 225789-38-8)

  Product features:

  Aluminum diethylphosphinate (ADP) is a kind of environmentally friendly flame retardant of phosphorus and nitrogen system. It is a white powder, organic phosphinate, insoluble in water and organic solvents such as acetone, dichloromethane, methyl ethyl ketone, toluene and so on. . It has the characteristics of high-efficiency flame retardant, high thermal stability, non-toxic, low smoke, small particle size, small specific gravity, good dispersion, etc. It can be widely used in thermoplastics (such as PA, PBT), fiber And the flame retardant of textiles, etc.

  Quality index:

  It is widely used in the flame retardant products of thermoplastics and thermoset plastics, fibers and textiles, such as thermoplastic elastomers, Flame retardant plastics such as polyoxymethylene, nylon (PA6, 66, etc.), epoxy resin, and polyester (PET, PBT). It can be used alone or in combination with flame retardants such as melamine polyphosphate, melamine cyanurate, etc, and its effect is better.

  ADP is especially suitable for polyester, it is suitable for glass fiber reinforced and non-reinforced grades. Flame-retardant polyester compounds have good physical and electrical properties. When added to PBT or PA66, the addition amount of diethyl phosphinate aluminum flame retardant is 13%-15% (parts by weight), and its material can reach UL 94 V-0 (1.6mm) when used as electrical accessories. The amount of flame retardant added will vary depending on the polymer grade, processing conditions and glass fiber addition.

  Before adding ADP, polyester materials should generally be pre-treated. If possible, the water content of the materials PBT and PET should be less than 0.05% and 0.005% (parts by weight), respectively. ADP does not need to be pre-dried. If the water content of the flame retardant is required to be very low, we recommend pre-drying (for example, drying at 130°C for 3 hours).

  Packing, storage and transportation:

  Keep in cool, dry and shading place.

  It is packed by composite paper bag or polypropylene woven bag, 25kg/bag,

  Handle with care during transportation.
