SF2800 – Sheet Material
A general purpose sheet material reinforced with aramid fibres and bound with nitrile rubber. Flexitallic SF2800 complies with the British Standard for non-asbestos sheet sealing materials – BS 7531 Grade Y.
Suitable for use across a broad spectrum of industrial applications involving steam (including super-heated steam), water, oils, solvents, fuels, gases, general chemicals, dilute acids and alkalis.
- Max Temperature: 400°C (750°F)
- Max Pressure: 12 MPa 1740 psig (120 bar)
Displaying excellent sealing characteristics, Flexicarb leverages the unique heat resistance of Thermiculite® to withstand temperature extremes from cryogenics through elevated levels.
Flexitallic Flexicarb is an exfoliated graphite material with standard grades at 95% to 98% and a nuclear grade available at 99.5%. It can be supplied with an inorganic passivating inhibitor to increase its oxidation and corrosion resistance. Recent experiences and tests have shown that Flexicarb will oxidize over time. Care should be taken when considering the use of Flexicarb foil for applications above 330°C (650°F).
Flexitallic Change™ has become the most significant development in the gasket and sealing industry in the past five years with more than 50,000 sold into sectors such as Steel, Power, Chemical, Refining, and Pulp and Paper, around the world.
Developed by Flexitallic in direct response to customers’ long-term heat exchanger sealing problems, Flexitallic Change™ is a highly-resilient metal-wound gasket, designed to deliver the most dynamic static sealing technology ever. Manufactured using proprietary equipment, Flexitallic Change™ has a proven track-record showing it outperforms conventional gasket technology in challenging environments, especially in applications with mechanical and thermal cycling conditions.
It has also achieved independent industry accreditation from TA Luft for its ability to deliver the tightness of a Kammprofile with the recovery of a Spiral Wound Gasket.
This is achieved through the application of a unique metal spiral profile, which is more advanced than those found in standard gaskets. This profile, combined with a laser welding process, facilitates the construction of a robust and dynamic seal.
