Pure Expanded Flexible Graphite Sheet

• Product Overview

Pure expansion flexible graphite sheet is a high-performance sealing material, mainly used in packing rings, winding gaskets, general packing, and various types of gaskets made from metal stamped composite plates or laminated (bonded) composite plates. It is specifically designed to provide reliable sealing performance in harsh industrial environments.

• Core Features

1. Ultimate Thermal Conductivity: With an in-plane thermal conductivity coefficient of up to 100-600 W/(m · K), it can quickly diffuse local hotspots into a uniform surface heat source, making it a "heat dissipation tool" for 5G communication, consumer electronics, and power modules.
2. Wide temperature range and corrosion resistance: It can withstand temperatures of 3000 ° C in an inert atmosphere and can be used in air for a long time at temperatures of 450-650 ° C. It has strong resistance to strong acids, bases, and organic solvents, and is halogen-free, sulfur free, and does not corrode metal flanges.
3. Excellent sealing and flexibility: with adjustable density (0.8-1.3 g/cm ³), it has excellent compression resilience and can adapt to rough or uneven surfaces, making it an ideal sealing substrate for high-temperature and high-pressure pipeline flanges and valves.
4. High purity and cleanliness: carbon content ≥ 99%, extremely low ash content (<1%), meeting the cleanliness requirements of semiconductor, photovoltaic, and food grade equipment.

Note: Customization is available for the product.

The Pure Expanded Flexible Graphite Sheet mainly addresses the core pain points of customers in four dimensions: heat dissipation efficiency, space constraints, high-temperature sealing, and material safety.

1. Solving the "heat dissipation bottleneck" and "temperature equalization problem"

• Pain point：5G chips, LED modules, and other heat sources have high power density, which can easily form local hot spots, leading to device frequency reduction and crashes. Traditional metal heat sinks have insufficient thermal conductivity and are difficult to quickly 'spread' the heat.
• The value of graphite solution：By utilizing its ultra-high in-plane thermal conductivity (100-600 W/(m · K)), it can quickly diffuse point heat sources to the entire plane like "ink absorbing paper", significantly reducing hot spot temperatures and improving equipment stability.

2. Breaking through the "narrow space" and "irregular structure"

• Pain points：Smartphones and wearable devices have extremely limited internal space, rigid heat sinks are too thick and heavy, and cannot fit the complex structure of curved or foldable screens.
• The value of graphite solution：extremely lightweight (0.03-0.1mm) and flexible and bendable. Perfectly fitting narrow spaces and irregular surfaces without increasing thickness or weight, solving the problems of "unable to fit" and "unable to stick tightly".

3.Dealing with "high temperature aging" and "sealing failure"

• Pain point：Industrial flanges and valves are prone to aging and decomposition of rubber/asbestos gaskets in high temperatures (>400 ° C) or corrosive media, leading to frequent leaks and high maintenance costs.
• The value of graphite solution：wide temperature resistance and chemical inertness. Maintaining stable compression resilience in high-temperature oil, acid, and alkali environments solves the stubborn problem of traditional sealing materials being "heat-resistant and prone to corrosion".

4.Eliminate material risks and EMI interference

• Pain points：Traditional asbestos gaskets have carcinogenic risks and high environmental pressure; Electronic devices also need to consider electromagnetic shielding (EMI).
• Value of graphite solution：asbestos free, halogen-free, in line with environmental requirements; Simultaneously possessing conductivity, it can also serve as an electromagnetic shielding material, with one material being versatile.

• The company has passed ISO9001 quality management system and ISO14001 environmental management system certification, demonstrating its outstanding pursuit in quality control and environmentally friendly production.
