Flame Retardant Lydorflam201 Crystalline Ammonium Phosphate (APP-II)
Description
Ø Molecular formula: [NH4PO3]n
Ø Ammonium polyphosphate (APP) is a kind of high quality, high efficiency, halogen free phosphorus nitrogen flame retardant.The product has high content of nitrogen and phosphorus, good thermal stability, neutral, non-toxic and low smoke.It is usually used in conjunction with other carbon sources and gas sources, and is an important part of all kinds of intumescent flame retardants and other flame retardant products. In the form of carbon and expansion mechanism play a role in heat insulation and flame retardance.
