MELAPUR 200
MELAPUR 200
Melapur® 200 (melamine polyphosphate) is a salt of melamine and polyphosphoric acid, suitable as flame retardant for glass fiber reinforced polyamide 66.
Applications
Melapur 200 is a melamine based halogen free flame retardant for glass fiber reinforced polyamide and polyester (e.g. PBT).
Features & Benefits
Melapur 200, 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 200provides a processing window of up to 320 °C. Excellent health and safety data offer additional handling and processing advantages.
