Abstract:
Shaped articles of melamine/formaldehyde foam have a formaldehyde emission of less than 0.1 ppm, determined according to DIN 55666, and are obtainable by the following process: a) a foam is prepared from a melamine/formaldehyde precondensate having a molar melamine: formaldehyde ratio greater than 0.5, b) the foam obtained is annealed at below 200° C., and c) the annealed foam is molded in a press at from 160 to 240° C. and an absolute pressure from 5 to 100 bar in the course of from 15 to 120 seconds to give the shaped article.
