GP 1520 - PURE GRAPHITE SHEET
Applications
Because of its specific structure expanded graphite sheets are particularly suited for applications with extremely high or low temperatures, with highly corrosive and aggressive media, for sensitive flange materials (i.e. enamel, glass, plastic) and for gas and steam applications.
Because graphite sheets are fragile and therefore difficult to handle, we recommend the use of styles with metal insertions. All styles are available with or without impregnation.
Construction
TEADIT expanded graphite sheets are produced from pure, expanded flexible graphite and do not contain any other fibers or filler materials.
Please note: the colour of the actual product might vary from the above image on this data-sheet.
Properties
TEADIT expanded flexible graphite sheets are universally applicable for gases and fluids. They are chemically resistant against most media, have excellent thermal conductivity, can be stored indefinitely, do not need anti-stick coating and are extremely resistant to temperature cycles.
