 agent component being present in different cartridges. The components, together with the remaining components, are expelled under pressure either by a blowing agent in the case of aerosol can foams, or by mechanical expulsion, and mixed in a static mixer, after which the mixture is introduced into the opening that is to be sealed, where it foams and/or cures. Pursuant to the invention, silicone foam systems can also be provided with the swellable polymers and used for the claimed application.
The plastic foams, which are to be used pursuant to the invention, can be open-cell or closed-cell foams. These pore forms are familiar to the expert and can be produced selectively in the foams by choosing the appropriate components. In this connection, the open-cell plastic foams are particularly preferred, because surprisingly it has turned out that, contrary to their anticipated larger porosity, they are significantly better than closed-cell foams in sealing the annular gap, which can never be quite avoided in the contact region between the plastic foam and the surface of the wall, floor or ceiling, or in sealing the openings, through which pipes, cables, pipelines, etc. are passed, if these devices, which are passed through the openings, have plastic surfaces of, for example, polyethylene, polypropylene or the like, which under normal circumstances exhibit only poor adhesion to the plastic foams in question.
The plastic foam system, which is used pursuant to the invention, contains the filler, which can swell in the presence of water, in an amount of 1 to 40% by weight, preferably of 5 to 30% by weight and particularly in an amount of 10 to 20% by weight, based on the weight of all the components of the plastic foam system.
In implementing the present invention, the components of the plastic foam systems, which contain filler that can swell in the presence of water, are produced in the usual manner, that is, the opening in the wall is foamed in situ with the foam system with the help of a foam dispenser or in a different manner. The foamed and cured foam fills the whole of the opening. Because of the foaming of the plastic foam system, a certain contacting pressure is already exerted by the foaming composition on these surfaces, which are to be sealed. Upon contact with water, such as the moisture of the surroundings, the swellable filler swells and a surprisingly large increase in volume takes place in the contact area, as a result of which further access of moisture into the cell structure

The component, in concert with the remaining components, are rout under imperativeness either by a blowing agent in the character of aerosol can foam, or by mechanical expulsion, and blend in a static mixer, after which the mix is introduced into the opening that is to be seal, where it foam and/or cures. Pursuant to the invention, silicone foam systems can besides be provided with the swellable polymer and use for the claimed application. 
 The plastic foam, which are to be used pursuant to the invention, can be open - cellular telephone or closed - cellular telephone foams. These pore forms are familiar to the expert and can be produced selectively in the foams by choosing the appropriate component. In this connection, the open - cell plastic foams are particularly preferred, because surprisingly it has turned out that, contrary to their anticipated larger porosity, they are significantly better than closed - cell foams in seal the annular gap, which can never be quite avoided in the liaison area between the plastic foam and the surface of the wall, floor or ceiling, or in sealing the opening, through which pipes, cables, pipelines, etc. are passed, if these device, which are passed through the openings, have plastic airfoil of, for example, polyethylene, polypropylene or the like, which under normal circumstances exhibit merely poor adhesiveness to the plastic foams in question. 
 The plastic foam system, which is practice pursuant to the invention, contains the filler, which can swell in the presence of water, in an amount of 1 to 40% by weight, preferably of 5 to 30% by weight and peculiarly in an amount of 10 to 20% by weight, based on the weight of all the components of the fictile foam system. 
 In implement the present invention, the components of the fictile foam systems, which check filler that can swell in the presence of water, are produced in the common manner, that is, the opening in the wall is foamed in situ with the foam organization with the help of a foam dispenser or in a different manner. The foamed and cured foam fills the whole of the opening. Because of the foaming of the fictile foam system, a certain contacting press is already exerted by the foaming composition on these surfaces, which are to be sealed. Upon contact with water, such as the moisture of the environment, the swellable filler swells and a surprisingly large increase in volume take home in the liaison sphere, as a result of which further access of moisture into the cellular telephone structure
