    摘要: 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 an ethylene-propyleneterpolymer (EPDM) thermoplastic material. Preferably, the thermoplastic material is embedded in polypropylene particles. The resulting seal has a contact portion which bends and/or compresses upon being engaged by a lid of a filter housing as the lid closes.

    摘要: 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.

    摘要翻译: 用于具有过滤器组件的过滤元件的密封件通过使用无细胞热塑性材料将密封件注射到过滤器组件上而产生,该过滤器组件具有邻近其中一个面的周边的密封件。 优选地,热塑性材料由嵌入在乙烯 - 丙烯共聚物(EPDM)中的热塑性颗粒组成。 所得的密封件具有接触部分,该接触部分弯曲而不是压缩在容纳过滤器元件关闭的壳体的盖上。
