| Zusammenfassung: | Seals for filter elements having filter packs with seals around the periphery thereof adjacent to one of the faces are produced by injection molding the seal onto the filter pack using a cell-less thermoplastic material. Preferably, the thermoplastic material is comprised of thermoplastic particles embedded in ethylene-propyleneterpolymer (EPDM). The resulting seal has a contact portion which bends rather than compresses upon a lid of a housing containing the filter element closing. |
