LEADERTHERM NXT

THE NEXT GENERATION IN EXTREME TEMPERATURE SEALING

<<INNOVATION BY LEADER GASKET NOW BAM APPROVED FOR OXYGEN SERVICE>>

Leader Gasket’s newest innovation on extreme temperature solutions has received great interest in several markets!

LeaderTHERM NXT is a modified phlogopite base material designed for critical high-temperature services such as turbochargers, catalytic cracking systems, power generation, gas boilers and equipment, and NOx containing applications.

Due to the very low weight loss at high temperatures (up to 1000°C/1832°F) of the modified phlogopite base material, LeaderTHERM NXT offers not only being extremely temperature resistant but also exhibit very low leakage in combination with practically no loss of gasket seating stress.

LeaderTHERM NXT exceeds in performance compared to other high-temperature materials in a thermal cycling leakage test. Data studies are available upon request exhibiting LeaderTHERM NXT sealing superiority.

Phlogopite is an important and relatively common end-member composition of biotite. Phlogopite micas are found primarily in igneous rocks, although it is also common in contact metamorphic aureoles of intrusive igneous rocks with magnesian country rocks and in marble formed from impure dolomite.

LeaderTHERM NXT also is an ideal alternative for graphite gaskets that are attacked by oxidation (>1000°C/1832°F).

TESTED AND PROVEN

BAM APPROVAL OXYGEN SERVICE AT HIGHEST TEST CONDITIONS

LeaderTHERM NXT is recently positively tested by the German BAM (Bundesanstalt für Materialforschung and –Prufüng) for Oxygen Service in accordance EN 1797 and ISO 21010 “ Cryogenic Vessels – Gas/ Material Compatibilty”. Material proven to be sufficient at a final oxygen pressure of 263 bars with autogenous ignition temperature that is greater than 500°C being the maximum operating temperature of BAM testappatus.

TA LUFT CERTIFICATION

Both LeaderTHERM NXT style 1000 Spiral Wound and style 1010 Kammprofile version are compliant with tightness criteria according TA Luft [10-4 mbar . l/(m . s)] as per Guideline VDI 2440 (Nov. 2000) and 2200 (June 2007) with rated high-grade srsling system for the purposes of TA Luft.
