Description:
LeaderTHERM Sheet consists of phlogopite mica paper impregnated with a high quality silicone binder.
Features:
Mica, an aluminosilicate of mineral origin, has a lamellar and non-fibrous structure representing an excellent alternative to asbestos at high temperatures. This material gives LeaderTHERM Sheet its thermal characteristics – weight loss at 800 C (1472 F) less than 5% – and its chemical resistance to solvents, acids, bases and mineral oils.
Service:
LeaderTHERM Sheet is developed specifically for high temperature applications (up to 1000C) as a sheet material, filler for spiral wound gaskets or facing for Kammprofiles. The material offers outstanding resistance to elevated temperatures as well as good sealability at moderate pressures.
Applications:
Exhaust manifolds, gas turbines, gas and oil burners, heat exchangers.
Operating Limits:
- Maximum continuous service temperature 1800F
- LeaderTHERM Sheet rated to a maximum of 80 psi.
- Spiral wound style *SRI-LTD rated to 1500F for ASME B16.5 Class 150 to 2500
- Spiral wound style SRI-LT (LeaderTHERM “only” filler) consult with LGT engineering dept.
- LeaderCAM with hybrid facing (inhibited graphite and LeaderTHERM combination) rated to 1500F for ASME B16.5 class 150 to 600 (1450 psi max.)
* Hybrid spiral wound gasket with (3) LeaderTHERM wraps on O.D. and remaining wraps of inhibited grade graphite. Oxidizing processes will require an additional (3) wraps of LeaderTHERM on I.D.
Availability:
In rolls or sheets or as winding strip for spiral wound gaskets. Available thicknesses:
0.8mm, 1.0mm, 1.5mm, 2.0mm, 3.0mm
Storage:
Should be stored in a cool dry place away from sources of humidity.
