MT Thermosphere®
Mouldable high temperature insulation paste
MT Thermosphere® is a low density
temperature resistant paste with excellent
thermal insulation properties from
cryogenic to high temperature exposure. It
is a perfectly seamless insulation system.
MT Thermosphere® is self drying and
mouldable. It dries by the evaporation of
the water content. If required, it can be
finished by painting or the application of
a covering material.
Properties
• Formulation based on glass microspheres in
inorganic binder.
• Capable of continuous single sided exposure
to 650 oC (approx.1200 oF).
• Non-combustible to Euro Class A1.
• Paste will air dry but drying can be
accelerated by heating to no higher than
90 oC (approx. 195 oF).
• No shrinkage when drying.
• Good thermal insulation.
• Low density / low weight.
• Suitable for insulation of complex shapes in
inaccessible areas.
• Environmentally safe.
• Hydrophobic.
Applications
Typical application temperature
range from -20 to 600 oC
(approx. 0 to 1110 oF).
Typical applications could include • Precast shapes for pipes and
difficult areas.
• Penetration seals.
• Gap sealing in insulation systems
for continuity of protection.
• On site repairs of existing
insulation systems.
• Any application where
conventional insulation block or
panel is difficult to use.
