Processing examples of D5400 expanded graphite large-diameter gaskets.
Supports duct gaskets with cross rubber coating processing.
■Overview of Processing Example Product Name: Gasket for Duct Dimensions: 4.8t 480φ × 380φ This processing example involves the production of a large-diameter ring-shaped gasket using cross processing. It utilizes glass cloth graphite-treated material, suitable for duct sealing applications in high-temperature environments. It has been adopted in the chemical equipment sector under conditions that require heat resistance and stable sealing performance. The cross rubber coating process ensures uniform shape accuracy and flexibility even for large diameters, achieving both workability and long-term sealing performance. ■Product Features | D5400 (with Expanded Graphite) This gasket is made by applying natural rubber to glass cloth and further combining it with expanded graphite. It offers excellent thermal insulation and is environmentally friendly as it is non-asbestos based. Various processing methods, including sewing, are available, allowing for large-diameter processing. The addition of expanded graphite enhances sealing performance and heat resistance, making it suitable for high-temperature duct sealing applications.
basic information
■Processing Method | Rubber Coating Rubber coating is a technology that creates high-performance composite materials by adding the diverse functions of rubber to the excellent heat resistance of the base material. The rubber coating makes it easier to process glass cloth through cutting, punching, and sewing, facilitating the production of complex shapes such as gaskets and ducts. The material can be laminated and shaped to the desired thickness. We can recommend the optimal material based on the usage temperature.
