The present application relates to a thermally expandable preparation which can be pumped at application temperatures in the range from 50 to 120 ° C., containing at least one polymer selected from binary copolymers containing at least one monomer unit selected from vinyl acetate, (meth) acrylic acids, styrene and their Derivatives and terpolymers based on at least one first monomer selected from monounsaturated or polyunsaturated hydrocarbons, and at least one second monomer selected from (meth) acrylic acids and their derivatives, and at least one third monomer selected from epoxy-functionalized (meth ) acrylates, as well as combinations of the first two; at least one liquid polymer selected from liquid hydrocarbon resins, liquid polyolefins and liquid polymers based on one or more diene monomers; at least one peroxide; at least one thermally activatable blowing agent and at least one adhesion promoter. Processes in which such preparations are used to stiffen / reinforce or seal components as well as the corresponding use are also recorded. |
