Product introduction
N-35/A melamine polyphosphate MPOP is composed of melamine and five oxidation
two phosphine polyphosphoric acid. It is an intumescent flame retardant, mainly nitrogen,
phosphorus and carbon as the core component. The system itself has a synergistic
effect, and there is no need to add other synergist. It has good compatibility in
polypropylene, polyethylene and other plastics, and has little influence on the mechanical
properties of plastics. Meanwhile, it has excellent processing stability in processing.
The flame retardant is made up of three parts: carbon source (carbon forming agent),
acid source (dehydrating agent) and gas source (foaming agent). Therefore, when burning,
(1) a compact carbon layer is produced, which can heat insulation and isolate air to achieve
the purpose of flame-retardant. (2) the heat release of CO2, NH3, N2 gas and H2O
reduces the oxygen in the air and the combustible gas produced by the thermal
decomposition of the polymer. (3) the heat generated up to absorb large quantities
of H PO free radical and HO free radicals, thereby preventing the combustion process,
combustion process of adding the flame retardant plastics, and achieve the purpose of
flame retardant by generating dense carbon layer expansion can insulate heat insulate air,
with smoke suppression and anti drop until the efficacy. Therefore, the amount of smoke
in the combustion is very small, and the corrosive toxic gas will not be produced.
(1) it has no hygroscopic, synergistic effect of phosphorus and nitrogen, and the effect
of flame retardant is superior.
(2) good thermal stability under all kinds of spontaneous combustion environment.(3) fine particle size, white color, good dispersion, mixed with plastic and rubber, can obtain
a uniform and good appearance.
(4) good effect of flame retardancy, no dropping, good compatibility, good dispersion, no
precipitation, and excellent coloring property.
(5) high thermal stability, good mechanical properties, especially excellent impact resistance.(6) it has anti dropping and excellent electrical properties, and is especially suitable fo
r electrical or electronic industry.
(7) in the process of combustion, the flame retardant effect of heat insulation and isolation
air is achieved through the expanded carbon layer which produces a dense speech, and
no toxic smoke such as hydrogen halide gas will be produced.
Calcium carbonate can not be added, and the addition of other inorganic filler should be
carefully evaluated in order to avoid the influence of the structure of the carbon layer
and influence the effect of the alkene resistance.
