Ammonium Polyphosphate (Specially for Textile Back Coatings )
Molecular formula: (NH4PO3)n, n>1000 CAS No.: 68333-79-9 EINECS No.: 269-789-9 HS CODE: 2835.3990 Model No.: TF-212
Product introduction
TF-212 is a phosphorus containing non-halogen flame retardant dedicated based on epoxy resin coated APP for textile coating.
Features
1. Halogen-free and none heavy metal ions.
2. Low water solubility, migration resistance. Good fluidity, not easy to cluster.
3. Good compatibility with acrylic emulsion, 212 is superior to 211 in hot-water-stain-resistance.
Product Usage
Suitable for all types of flame-retardant textile coatings, especially for hot-water-stain-resistance acrylic emulsion coatings. 212 is also suitable for other flame retardant fields that require higher water resistance and higher mechanical properties.
Compared with 201, 212 works better in polyurethane emulsion, polyurethane glue, epoxy flame retardant and various resins.
