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.
