Abstract
The resistance to internal charring of molded styrene-butadiene latex foam rubber when exposed to a lit cigarette is improved by incorporating from about 10 to 30 parts by dry weight, per hundred parts by dry weight of latex of a compound selected from the group consisting of an organic phosphate of the formula ##STR1## wherein R is a C.sub.6-12 alkyl radical or a phenyl radical, which is unsubstituted or substituted by a C.sub.1-4 alkyl radical, butyl benzyl phthalate, and a mixture thereof.
