Supports split structure with cross rubber coating processing.
■Overview of Processing Example Product Name: Jigsaw Split Gasket Dimensions: 400φ × 291φ This processing example involves the production of a jigsaw split gasket with a segmented structure using cross rubber coating. By incorporating a split in the circumferential direction, it allows for installation and replacement without disassembling the equipment, making it suitable for applications that require improved maintenance. It is primarily used in equipment designed for on-site construction, such as blowers and duct connections, and can be retrofitted to existing machinery. The split sections are designed with positioning considerations to minimize misalignment during assembly, ensuring stable sealing performance. By adopting cross rubber coating, it leverages the material's flexibility and moldability while achieving uniform thickness and high precision in the finish. ■Product Features | D5400 This gasket is made by applying natural rubber to glass cloth and molding it into a specified shape. It has excellent thermal insulation properties and is environmentally friendly as it is non-asbestos. There are various processing methods, including sewing, allowing for large diameter processing. It is used for high-temperature duct sealing.

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 layered and shaped to the desired thickness. We can recommend the most suitable materials based on the operating temperature.
