Grade: Flexible Graphite
Formula: C
Form: Foil (Light Tight)
Material: Carbon
CAS Number: 7440-44-0
Commodity: Metals
Purity:
99.8%
Light Tight:
Light Tight
Goodfellow's flexible graphite carbon foil (light tight) is a carbon-based foil product notable for its flexibility and opacity to light. With a density of just 1.1 g/cm3, this lightweight foil can readily conform to curved surfaces while completely blocking the transmission of light. Key applications of this versatile foil include its use as a high-temperature gasket material in optical devices and as an electromagnetic shielding material in electronic enclosures where both flexibility and light-blocking ability are required. As part of Goodfellow's extensive range of foil products, this graphite foil offers unique combinations of physical, electrical and optical properties.
