Solutions And Customized Services Provided
High purity Graphite Roll is essentially an industrial flexible material that is resistant to high temperatures, has good thermal conductivity, and is also sealed. It mainly solves the three core pain points of sealing failure, heat dissipation bottleneck, and installation efficiency for customers in extreme environments.
Difficult to seal at high temperatures-Flanges and valves are prone to leakage above 300 ℃, rubber may burn, and metal gaskets may creep.
High purity Graphite Roll is a high-temperature resistant seal that maintains elasticity from -200 ℃ to 800 ℃ (higher under inert atmosphere), without melting or aging, solving the problem of high-temperature leakage and dripping.
Low heat dissipation efficiency-5G base stations, lithium batteries, and high-power devices generate a large amount of heat, while traditional materials have slow thermal conductivity.
High purity Graphite Roll for efficient thermal management, with high planar thermal conductivity (150-250 W/m · K), can quickly dissipate heat from the heat source and reduce equipment operating temperature.
Poor corrosion resistance-Chemical pipelines come into contact with acid and alkali, and metal gaskets are prone to corrosion and perforation, leading to production stoppage.
High purity Graphite Roll has inertness, acid and alkali resistance (except for strong oxidants), low ash content, and will not react with the medium, extending equipment life.
Low installation efficiency-Customized molds are required for sealing large equipment, resulting in long lead times and high costs.
High purity Graphite Roll is flexible and customizable, with a roll shape that allows customers to cut any shape and size on site as needed, without the need for mold opening and with fast response speed.
