Crinkled Graphite Tape

Crinkled Graphite Tape is a high-performance functional material made from high-purity natural flake graphite, processed through precision CNC cutting and special crimp forming technology. Its core value lies in perfectly combining the natural physical and chemical properties of graphite with the sealing and thermal conductivity requirements in engineering applications via its unique corrugated structure design, providing reliable material solutions for extreme working conditions.

Ultra-high Purity Base Material: Carbon content ≥ 99%, free of additives such as fibers and binders, with sulfur content ≤ 1000ppm and chlorine content ≤ 50ppm, meeting strict industrial cleanliness requirements.

Extreme Environment Resistance: Temperature resistance ranges from -200℃ to 450℃ in air atmosphere, and from -200℃ to 3000℃ in inert atmosphere; it can withstand a static pressure of 130bar, suitable for full-scenario applications from deep cooling to high temperature.

Superior Sealing Performance: Compression rate ＞ 40%, rebound rate ＞ 12%; the elastic deformation of the crimped structure realizes dynamic sealing compensation, significantly reducing medium leakage rate.

Broad Medium Compatibility: Features broad-spectrum corrosion resistance with pH 0-14, showing excellent stability against hot water, steam, organic solvents, acids, alkalis, etc., suitable for complex chemical environments.

Strong Engineering Adaptability: Thickness ranges from 0.1mm to 1.5mm, width can be customized from 2mm to 1500mm; supports adhesive-backed (Model 2020-zh) and non-adhesive (Model 2020-z) designs, enabling easy installation and on-demand cutting.

 

 

Industrial Sealing Systems: Used as the core material for pump and valve packing and flange gaskets, widely applied in static and dynamic sealing scenarios of equipment such as chemical pipelines, pressure vessels, and heat exchangers.

Automotive & New Energy: Utilized for engine valve stem sealing and battery pack thermal buffer layers, meeting both sealing reliability and thermal conductivity requirements under the working condition of -40℃ to 125℃.

Electronic Thermal Management: With an in-plane thermal conductivity of 140W/m·K, it serves as a flexible thermal interface material, acting as a thermal conduction bridge between power devices and heat sinks.

Extreme Working Condition Engineering: In nuclear industry, aerospace, and other fields, it undertakes high-temperature sealing and thermal protection functions in inert gas environments.

This product has passed multiple international and domestic standard certifications, including ASME B 16.20 and GB/T 4622.2. It can be customized into nuclear-grade versions (carbon content ≥ 99.5%) according to customer needs to meet more stringent performance requirements. Its additive-free pure graphite structure and recyclable properties also comply with the environmental protection and sustainable development needs of modern industry.
