Material composition:  
SinoSeal expanded graphite sheets are produced from pure, expanded flexible graphite and do not contain any other fibers or filler materials.

SinoSeal 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: 70 bar
carbon content: > 98 %
chloride content: < 30 ppm
sulphur content: < 1000 ppm
density (graphite): 1g/cm3
compressibility:  40 - 50 %
recovery:  10 - 25 %
residual stress: > 45 N/mm2

Product standard:
sheet size (in mm): 1.000 x 1.000 , 1500x1500.
thickness (in mm): 1,0 / 1,5 / 2,0  and 3,0
The following styles of expanded graphite sheets are available:
SINOSEAL GP 1520: pure expanded flexible graphite.
SINOSEAL GE 1520/SS304: pure expanded flexible graphite with tanged metal insert in SS304 (0,1mm)
SINOSEAL GE 1520/SS316: pure expanded flexible graphite with tanged metal insert in SS316 (0,1mm)
SINOSEAL 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.
