Abstract: A system for producing an in-situ foam, which comprises the components from 50 to 98% by weight of one or more inorganic fillers A), from 1 to 48% by weight of one or more water-soluble, cationic polymers B), from 0.5 to 48% by weight of one or more surfactants C), from 0.01 to 5% by weight of one or more crosslinkers D) which are capable of reacting with the polymers B), from 0 to 20% by weight of one or more additives E), where the percentages by weight of the components A) to E) are based on the nonaqueous fraction and the sum of A) to E) is 100% by weight, process for producing an in-situ foam using the components of the system and foaming by means of a gas or a gas mixture and use for thermal insulation and filling of hollow spaces and hollow bodies.
