Flame Retardant for Textile - EPFR-APP222



Preniphor™ EPFR-APP222 is highly recommended for textile coating.


EPFR-APP222 is a kind of high polymerization degree and crystal typeⅡ ammonium polyphosphate without activation or surface treatment. It has low viscosity ,high content of Phosphorus & Nitrogen, excellent thermal stability, near-neutral and non-toxic smoke property. With gas source and carbon source, it takes effect by char formation and intumescent mechanism.


EPFR-APP222 used in textile coating can meet requirement of GB 17591,GB 20286,BS 5852,FMVSS 302.
