MELAPUR® 200/70
Halogen free melamine based flame retardant for glass fiber
reinforced PA66
Characterization MELAPUR® 200/70 (melamine polyphosphate) is a salt of melamine and polyphosphoric acid,
suitable as flame retardant for glass fiber reinforced polyamide 66.
Chemical name Melamine-polyphosphate
CAS number 218768-84-4
Applications MELAPUR 200/70 is a melamine based halogen free flame retardant for glass fiber reinforced
polyamide 66
Features/benefits MELAPUR 200/70, melamine polyphosphate, is a halogen-free flame retardant specially developed
for glass fiber reinforced polyamide 66. As a white powder it opens up new and broader color
schemes for flame retarded glass fiber reinforced PA 66. The mechanism is based on intumescence.
At exposure to fire a strong and stable char is formed which protects the polymer and prevents
further flame propagation.
The good balance between intumescence and thermal stability of MELAPUR 200/70 provides a
processing window of up to 320 o C. Excellent health and safety data offer additional handling and
processing advantages.
