Sigraflex Sondertyp

Description:
SIGRAFLEX SONDERTYP is composed internally of 0.025mm thK. AISI 316 L steel laminations and expanded graphite layers with ash content of less than 2.00%.
The anchoring between the various layers of materials takes place without the use of adhesives or the like but through a patented SGL Group system.
This gasket is particularly suitable for use on toxic, flammable or polluting substances that require low fugitive emission values.
It can also be used in systems with Fire - Safety requirements.
Sigraflex SonderTyp has excellent oxidation resistance and good chemical resistance.
The Sigraflex SonderTyp gaskets meet the requirements of the Atex standard (CEI 31-35 guide).

  • Ideal for use on zero emission applications
  • Graphite impregnated with corrosion inhibitor
