Abstract: An elastic oblong seal has a sealing section with a flexible outer body and a rodent resistant barrier therein. The barrier includes separate metal wires arranged at a distance to each other and extending substantially in parallel to a seal longitudinal direction. The outer body includes a TPE constituting the basic material and form of the seal. The metal wires include at least three separate metal wires each of solid single stranded metal. At least two of the at least three are encompassed by a TPE which is at least one chemically modified PP, selected from the group consisting of: a PP grafted with carboxylic acid, PP grafted with anhydride groups, a PP grafted with epoxides, a PP grafted with silanes, a MAPP, a PP grafted with methacrylic acid, a PP grafted with glycidyl methacrylate, a PP grafted with vinyl trimethoxysilane, and a PP grafted with methacryl trimethoxysilane.

Abstract: A flexible and oblong blade seal for sealing a gap between a door leaf and an adjacent surface includes A) a flexible outer material and B) a section with the sealing function (the sealing section), in which a barrier of a plurality of substantially parallel metal wires and/or narrow metal strips is embedded in the flexible outer material in such a way, that the wires and/or strips are arranged in parallel to the longitudinal direction of the seal. A method for mounting such seals and a method for producing them.
