Fumed Silica Film
SNG (gas-silicon) is a high-barrier film developed for gas-silicon vacuum insulation panels. It has excellent anti-aging, oxygen and water resistance properties. The porous structure of the gas-silicon film has a strong adsorption effect on water vapor and is resistant to external pressure With low sensitivity and longer lifespan, it is suitable for scenes requiring long lifespan, such as construction.
