description |
Melamine Pyrophosphate (Melaflam®MPY) is a white
free flowing crystalline powder, non-halogenated,
phosphorus based flasme retardant useful by itself
or as an adjuvant for flame retarding various thermoplastics,
polyolefins, elastomers, engineering resins, paints
and intumescent fire retardant coatings, it can
partly replace Ammonium Polyphosphate(APP) due to
its excellent flame retardant mechanisms.
Melaflam®MPY can also be used in non-polymer fields
covering Epoxy, Paper, Paint, Wood Laminates to
effect fire retardant barriers. Melaflam®MPY is
useable for Dipentaerythritol as well as polyolefins,
and available for SMC process (unsaturated polyester
resins), Melaflam®MPY can be also used together
with ammonium Polyphosphate (as an intumescent resource
and catalyst) in some intumescent flame retardant
applications. |

Flame
Retardant Mechanisms |
Because of the synergism of combination of Nitrogen
and Phosphorus, only a small injection dosage is
required for formulation achieving UL 94 V-0 grade
flame retarding, due to Acidic catalysis, inert
gas formation and foaming, flames shall be retared
and eliminated effectively.
Melamine Pyrophosphate doesn't contribute to formation
of toxic gases.

Application Guide: |
Melaflam®MPY can be processed up
to 300℃on typical polymer processing
equpment such as single or twin screw extruders,
internal batch mixer (Banbury typ) and roll mills.
Molding operations such as injection molding and
thermal forming processes are easily accomplished
with composites made of this flame retardant.
28-30% Melaflam®MPY is the suggested
adding dosage for Polymer or Intumescent Coatings.

Cost comparison
with other halogenated flame retardants |
Cost savings can be achieved with Melaflam®MPY
composites over halogenated systems due to the density
difference of the flame retadants, i.e. the halogenated
systems contribute signficantly more to the composite's
density. Therefore, more more composite of Melaflam®MPY
compound can be produced for the same weight. Another
benefit over other halogenated materials is the
reducation of smoke generated with the combustion
of compounds prepared with Melaflam®MPY
(measure optically by somke subscription, ASTM-2483).
