Graphite paper is primarily composed of a layered structure of carbon atoms. Its density is low (typically 0.7-2.0 g/cm³), making it soft yet mechanically strong. Its thermal conductivity can reach 1000-3000 W/(m·K), approaching that of metallic copper. It also possesses excellent chemical stability and resistance to acid and alkali corrosion. However, these characteristics also require special attention during logistics:
1. Fragility and Risk of Mechanical Damage
Although graphite paper is relatively flexible, its layered structure makes it susceptible to delamination or cracking when subjected to severe bending, folding, or squeezing. Therefore, during transportation, it is important to avoid severe vibration, heavy pressure, or improper stacking. Graphite paper is typically protected with cushioning materials (such as bubble wrap or EPE foam) and secured in sturdy packaging.
2. Electrostatic Sensitivity
Graphite paper has high electrical conductivity, but in dry environments, friction can cause static electricity to accumulate, affecting its performance or attracting dust. Therefore, anti-static measures should be taken during packaging, such as using anti-static bags or lining materials, and humidity control during transportation (relative humidity is recommended to be maintained between 40% and 60%).
3. Environmental Adaptability
Although graphite paper is corrosion-resistant, extreme temperatures (such as prolonged exposure above 200°C or below -40°C) can cause structural changes, affecting its thermal and electrical conductivity. Therefore, high temperatures should be avoided during transportation, and a constant temperature (recommended between 10°C and 30°C) should be maintained. Especially during high summer temperatures, insulation or refrigeration should be employed.
