THERMOFORMABLE MELAMINE/FORMALDEHYDE-BASED FOAMS EXHIBITING LOW-FORMALDEHYDE EMISSION

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...

Zusammenfassung:	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. ® KIPO & WIPO 2008
