20250230105. Mineral-based Expanding Foam (Wacker Chemie AG)
MINERAL-BASED EXPANDING FOAM
Abstract: a mineral expanding foam is based on one or more foam stabilizers, one or more air pore formers selected from the group comprising ammonium salts or alkali metal salts of the hydrogencarbonates or carbonates, optionally one or more fillers, and optionally one or more additives. the mineral expanding foam is additionally based on one or more protective colloid-stabilized polymers of ethylenically unsaturated monomers in the form of aqueous dispersions or water-redispersible powders, one or more latent air pore formers selected from the group comprising aluminum and silicon and alloys thereof and calcium carbides and 30% to 95% by weight, based on the dry weight of the mineral expanding foam, of cement. the proportion of latent air pore formers is ≥10% by weight, based on the total weight of air pore formers and latent air pore formers
