Natural rubber diaphragm filter plates and diaphragm sheets are critical components in filter presses used for specialized industrial applications. Their primary functions are to provide a reliable seal and withstand high operational pressure during the filtration cycle, enabling efficient solid-liquid separation.

These filter plates are typically manufactured from high-grade natural rubber. To enhance structural integrity and stability, the rubber is often reinforced with an internal steel plate. Through specialized processes like hot vulcanization, the rubber is permanently bonded to the steel core, creating a unified, monolithic structure.
