But in real applications, what matters is the conductivity of the film, coating, or network created by millions of flakes. That depends on more than intrinsic flake conductivity: → flake size → flake thickness → defect density → flake-to-flake contact resistance → distribution in the final material system This is why graphene production methods matter. Graphene oxide can disperse well, but defects reduce conductivity. Mechanically exfoliated graphene can be conductive, but smaller flakes increase the number of flake-to-flake contacts. eGraphene is designed differently: large lateral flakes (~0.5–1 µm), few-layer thickness (<3 nm), and controlled surface functionality — enabling conductive networks with measured bulk conductivities up to 140,000 S/m.

Not all high-temperature fibers clear this bar. Refractory ceramic fibers (RCF) do not meet this standard. Some polycrystalline wools (PCW) do not either. AES fibers can qualify but cannot reach such high temperatures (1600°C, 2912°F), limiting their high temperature applications. VSG's bulk and alumina fiber needled blankets meet the classification threshold without giving up thermal performance. For engineers and EHS teams specifying insulation materials in high-temperature environments, this has practical consequences. Fewer handling restrictions. Cleaner compliance documentation. No trade-off on performance...

The reason is simple: fibers carry load most efficiently when aligned with the applied forces. As a result, different reinforcement formats can deliver very different tensile properties, even when manufactured from the same glass fiber. 🕵🏻‍♂️ Fiber volume fraction also plays a critical role. Increasing the proportion of fibers generally improves stiffness and strength, but only up to the point where manufacturing quality and resin distribution can still be maintained. The result? Two laminates made from the same material system can exhibit completely different structural behavior depending on how the fibe...
