ABSTRACT:
Phenolic foam having improved punking resistance is obtained by effecting the formation of phenolic foam in the presence of an aralkyl-modified polyalkylsiloxane. Used with particular advantage as non punking additives to phenolic foam formulations are polymethylsiloxane oils in which silicon is additionally bonded to phenylethyl groups.
