Ammonium Polyphosphate Water Soluble Paper Flame Retardant With Low
Arsenic Used For Textile Directly Contact With Skin
TF-304 is a water soluble APP with low arsenic less than 2ppm . Its
raw material is food grade. When it is used as flame retardant on
paper, textile, especially for textile ,it can be for textile
directly contact skin, such baby car seat.

Most flame retardants used for impregnation are ammonium phosphate
and water-soluble ammonium polyphosphate. In recent years,
guanidine phosphate and sulfonamide are often used, but the treated
paper easily absorbs water and feels bad.
1. Impregnating the base paper with flame retardant aqueous
solution / water dispersion
The flame retardant impregnation treatment method of paper products
is similar to that of wood. The flame retardant is usually
configured as a 10% -20% aqueous solution, an appropriate amount of
penetrant is added, and after a period of time is taken out, dried
and smoothed to obtain a flame retardant paper product.
Affected by the thickness of the paper, the dosage amount of flame
retardant is usually 10-20g / m2. The method is carried out outside
the papermaking equipment, the processing time is short, and the
operation is simple. Suitable for all kinds of raw paper,
decorative paper, wallpaper, construction paper, etc.
2. Cover the surface of the paper with a flame retardant solution
Use a flame retardant aqueous solution or flame retardant
dispersion to brush and spray on the paper surface. This method can
save the amount of flame retardant and is easy to operate, but can
only achieve the surface flame retardancy of thick paper, which is
not conducive to the overall flame retardancy of paper.
Flame retardants and adhesives are often used together to improve
the strength, abrasion resistance and water resistance of paper
