摘要： A composite, dynamic seal suitable for use in a high temperature environment and method of making same. The dynamic seal includes a resilient, generally ring-shaped seal body having a first layer formed of a first resilient sealing material and a second layer formed of a second resilient sealing material. The first and second layers are preferably molded and cured together simultaneously and chemically cross-linked to each other. The first resilient sealing material is selected for its wear resistant dynamic properties and the second resilient sealing material is selected for its compression set resistant properties. Preferably, the first resilient sealing material is tetrafluoroethylene and propylene copolymer and the second resilient sealing material is fluorocarbon rubber. The first and second resilient sealing materials have compatible cure systems, preferably peroxide cure systems.

摘要翻译： 适用于高温环境的复合动态密封及其制造方法。 动态密封件包括具有由第一弹性密封材料形成的第一层和由第二弹性密封材料形成的第二层的弹性的大致环形的密封体。 第一层和第二层优选同时模塑并固化在一起，并彼此化学交联。 选择第一种弹性密封材料的耐磨动态性能，并且选择第二种弹性密封材料用于其抗压缩变形性能。 优选地，第一弹性密封材料是四氟乙烯和丙烯共聚物，第二弹性密封材料是碳氟橡胶。 第一和第二弹性密封材料具有相容的固化体系，优选过氧化物固化体系。
