Ureum-formaldehyde

Ureum-formaldehyde (UF) is comparable to PF, but is somewhat stiffer and has, because of its colourlessness and gloss, a more attractive appearance. The applications are in the same fields as PF. 

Another whipped foam is ureum formaldehyde foam. A watery solution of ureum, formaldehyde and additives, is whipped to a very light foam. When this is dried at an elevated temperature, the resin is cured into a hard foam of a few kg/m3, to be applied in packaging and as artificial snow in shop-windows etc.
