Flame Retardant For Fireproof Coating - EPFR-APP222H



Among the PreniphorTM EPFR-APP (Ⅱ) series nitrogen-phosphorus inorganic flame retardants, Preniphor EPFR-APP222H is a kind of high polymerization degree, crystal type Ⅱ ammonium polyphosphate without activating and surface treatment. It has high content of phosphorus and 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-APP222H is highly recommended to intumescent coatings


Compared with other similar commercial products,at the same dosage, EPFR-APP222H has much lower viscosity in water, polyol suspension of polyurethane and better stability for long term storage.
