Ammonium Polyphosphate (Specially for textile back coatings) TF- 211
Molecular formula : (NH4PO3)n, n>1000 CAS No.: 68333-79-9 EINECS No.: 269-789-9 HS CODE: 2835.3990 Model No.: TF-211
Product introduction
TF-211 is a phosphorus containing non-halogen flame retardant dedicated for textile coating.
Features
1. Halogen-free and none heavy metal ions.
2. Stain resistance for hot water. Low water solubility, not easy to precipitate under high temperature and high humidity conditions.
3. Good compatibility with organic polymers and resins, especially acrylic emulsion.
Product Usage
Suitable for all types of flame-retardant textile coatings, especially for hot-water-stain-resistance acrylic emulsion coatings.

1.Prepare textile backing coating: Prepare the coating according to the formula and scratch it on the surface of black base textile (polyester fiber). The thickness of the coating ≤0.1mm, and heat-treat it in the oven at 120 ℃ for 3-5min, then the test sample was obtained.
2.Hot water stain test: 60-70 ℃ hot water drip on to the coated side of back coating textile, select 4 to 5 stains and drying them in the oven at 60-70 ℃ for 10min, the test results are as follows:
Packing : 25kg /bag, 24mt/20’fcl without pallets, 20mt/20’fcl with pallets. Other packing as request.
Storage: in dry and cool place, keeping out of moisture and sunshine, shelf life two year.
