SIGRAFLEX® APX2® Foil Yarns
We have responded to customer requests for high-temperature resistant and high-purity braided packing yarns with outstanding mechanical properties by developing a new yarn.
This has resulted in the best foil yarn on the market regarding oxidation resistance: The flexible expanded natural graphite yarn SIGRAFLEX APX2, made of SIGRAFLEX APX2 foil already established in the sealing market with Alloy 601 wire reinforcement.
SIGRAFLEX APX2 yarn combines a number of other unique properties including low friction, high flexibility, and excellent chemical resistance. Also, the yarn does not become brittle over time and just like SIGRAFLEX APX2 foil it exhibits high thermal conductivity so frictional generated heat can be easily transferred. Furthermore, it is PFAS-free.

Components
SIGRAFLEX® OXR Yarn
SGL Carbon’s new oxidation resistant yarn is the only coated textile packing yarn currently meeting the graphite requirements of the Shell specification MESC SPE 85/204 for graphite.
SIGRAFLEX® ECONOMY
Flat gaskets from SIGRAFLEX ECONOMY graphite sealing sheets are suitable for pumps, fittings and valves, especially for thin gaskets, for unstable flanges with low gasket stresses and for waste gas pipelines, e.g. in incineration plants as well as for raised-face flanges.
Sliding Rings Made of Carbon
SGL Carbon's high performance sliding rings are made of graphite, carbon graphite and expanded graphite. The inert properties of the material make them extremely resistant to both high temperatures and aggressive gases and superior to other materials. In addition, their excellent sliding properties ensure low-wear and low-noise operation.
