ABSTRACT:
The invention relates to a composition which can be foamed from pressurized containers. Said composition is based on an aqueous plastic dispersion containing an aqueous dispersion of at least one film-forming plastic material consisting of 30% to 80% by weight of a film-forming plastic material, a propellant gas amounting between 3% to 25% by weight in relation to the entire composition and one or more ionic foam stabilizers amounting between 0.3 and 6% by weight in relation to the entire composition. The foamed compositions can he used as scaling, damping and insulating materials.
