Physical and Chemical property: Crystallization II type ammonium
polyphosphate (APP**1) is the halogen-free and environment-friendly
flame retardant with nitrogen-containing structure that is high
degree of polymerization, thermal stability, small hygroscopicity.
It is different from the flame retardants of halogen-containing
that achieves flame-retardant effect of Insulating and isolating
the air by swelling carbon layers in the combustion process. It is
a highly efficient environment-friendly inorganic flame-retardant
materials that smoke-free, non-toxic, non-metal.
