Revision: Rev.: 01/08/2000 Material composition:
TEADIT expanded graphite sheets are produced from pure, expanded
flexible graphite and do not contain any other fibers or filler
materials.
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.
Application areas:
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.
Technical data:
Temperature range: - 240° C up to 450 ° C, with
steam up to 650 °C,in non-oxidizing atmosphere up to 800°C
pH range: 0 - 14
max. pressure: 140 bar
carbon content: > 98 %
chloride content: < 30 ppm
sulphur content: < 1000 ppm
density (graphite): 1g/cm3
compressibility: 30 - 40 %
recovery: 15 - 30 %
residual stress: > 45 N/mm2
Product standard:
sheet size (in mm): 1.000 x 1.000
thickness (in mm): 1,0 (only SS 316) / 1,5 / 2,0
and 3,0
The following styles of TEADIT expanded graphite sheets are
available:
TEADIT GP 1520: pure expanded flexible graphite.
TEADIT GE 1520/SS304: pure expanded flexible graphite with tanged
metal insert in SS304 (0,1mm)
TEADIT GE 1520/SS316: pure expanded flexible graphite with tanged
metal insert in SS316 (0,1mm)
TEADIT GR 1520: pure expanded flexible graphite with plain metal
insert in SS316 (0,05mm)
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.
