MAT OF POLYMER FIBRES CONTAINING AN ACETOACETAMIDE, AND ITS USE.

摘要

The present invention relates to a mat of polymer fibers capable of trapping formaldehyde which contains at least 0.5% by weight of an acetoacetamide of formula: in which R1 and R2, which may be identical or different, represent a hydrogen atom, a methyl radical or an ethyl radical. Another subject of the invention is the use of said mat, in particular as a surface covering for thermal and/or sound insulation products, in particular based on mineral wool, polystyrene or on an organic or inorganic foam.
