Expanded Pure Graphite

FLEXITECK (UK)

Style : 2300

UC UNIVERSAL

Graphite intercalation compounds are produced from the natural graphite flakes. Which are compressed into foils without binder or filler. Graphite sheets are manufactured in various forms, namely unreinforced, impregnated or reinforced. Absence of binders means no ageing or embrittlement. Long-term stability of compressibility and recovery over a wide temperature range. No cold or warm flow up to maximum permissible gasket stress. High creep strength under compressive stress. Properties highly anisotropic, particularly in respect of electrical and thermal conductivity. Resistance to radiation and thermal shock.
