Abstract

The present invention concerns a needle felt of mineral wool, in particular glass wool, which even at elevated temperatures does not release any toxic products, in particular no formaldehyde, into the surrounding atmosphere and therefore has optimum suitability for use as a heat insulating material in household appliances such as ovens or cookers. Freeness from formaldehyde of the needle felt results from utilisation of a novel needling aid on the basis of halogenated polymers, in particular fluorated polymers.
