PRODUCT SPECIFICATIONS AND DETAILS
Product Overview
Graphite Sealing Materials are high-performance graphite-based sealing products widely used in gaskets, packing, flange sealing, static sealing systems, and high-temperature industrial equipment. These materials are valued for their flexibility, compressibility, heat resistance, chemical stability, and ability to maintain sealing performance under demanding service conditions. Compared with conventional sealing materials, graphite sealing materials are better suited for applications involving elevated temperatures, pressure fluctuations, and aggressive media.
At QDZRT Graphene, Graphite Sealing Materials are supplied for industrial customers requiring reliable sealing performance, processing flexibility, and stable material quality. Depending on application requirements, these materials can be provided in the form of graphite sheets, graphite rolls, sealing rings, gasket sheets, reinforced graphite materials, and customized die-cut parts. Different specifications can be matched according to thickness, density, reinforcement structure, purity grade, and service conditions.

Main Applications
Flange and Static Sealing Systems
Graphite Sealing Materials are widely used in flange joints, valve bodies, pump housings, and other static sealing systems where sealing reliability is required under high temperature, pressure, or chemical exposure conditions.
Gasket Manufacturing
These materials are commonly converted into sheet gaskets, ring gaskets, die-cut gaskets, and custom sealing parts for industrial equipment. Reinforced and laminated grades can be selected for applications requiring better handling strength and structural support.
Packing and Valve Sealing
Graphite sealing materials are also used in packing-related systems and valve sealing applications where flexibility, compressibility, and resistance to service media are important for stable long-term operation.
Chemical and Petrochemical Equipment
Because of their chemical stability and sealing reliability, graphite sealing materials are widely used in chemical plants, petrochemical systems, processing lines, and industrial equipment exposed to demanding service environments. QDZRT Graphene supports customers seeking sealing materials suitable for different process conditions and industrial requirements.
Power Generation and High-Temperature Equipment
In boilers, heat exchangers, steam systems, and other thermal process equipment, graphite sealing materials are used to support sealing performance in environments involving heat, pressure fluctuation, and long operating cycles.
Customized Industrial Sealing Parts
These materials can be further processed into custom rolls, strips, washers, discs, gasket sets, and specially shaped sealing parts according to customer drawings and maintenance requirements. QDZRT Graphene can support both standard supply and application-specific customization.
