Foamed polyblends comprising a filled styrene-butadiene rubber are rendered attractively flame-resistant (e.g. for use as carpet underlay) without loss of "green strength" needed during processing (e.g. in a Banbury mixer) by blending therewith about 10-50 parts per hundred, based on the rubber, of a pre-fused vinyl chloride polymer plastisol.
