Description of Melapur M 200:
Melapur M 200 decomposes endothermically above 350ºC, acting as a heat sink to cool the polymer.

Melapur M 200 was applied as reactive and additive flame retardant for thermally resistant polyurethane foams.
Melapur M 200 was hydroxyalkylated with ethylene and propylene carbonates to get oligoetherols with 1,3,5-triazine ring and phosphorus.

The structure and physical properties of the products were studied.
The polyurethane foams, PUFs obtained from this oligoetherols were self-distinguishing.

The addition of powdered Melapur M 200 into foaming mixture resulted in further decrease of flammability modified PUFs.
The Melapur M 200-modified PUFs were characterized by physical methods adequate to thermal resistance and flammability of the PUFs.
