Abstract: The invention relates to a method for thermally producing foams by foaming and cross-linking a mixture which contains a melamine/formaldehyde (MF) precondensate, a hardener and a propellant, wherein a formaldehyde scavenger is introduced prior to heating. A thermoformable melamine/formaldehyde-based foams exhibiting a low-formaldehyde emission and the use thereof for producing parts shaped by thermoforming are also disclosed.
