Material Description
PROMALAN®-CR is a resin-bonded
mineral wool board with mainly vertically-
oriented fibre structure.
PROMALAN®-HT 400 is a strong mineral
wool board with organic-inorganic binder.
The products are harmless with regard to
working hygiene and are not subject to
any classification.
Advantages and Properties
• large-sized
• clean cutting and machining
• can be used on fire side
• high hot compression strength
• low thermal conductivity
• high sound-proofing value
Working and Processing
The PROMALAN®-CR/-HT insulating
boards can be easily worked with wood-
working machinery and tools. A variety of
fixing and connecting systems is available
for dimensionally stable cut sections with
clean-cut edges, depending on the con-
struction and thermal and mechanical
load.
Cut Sections
Shaped parts and cut sections are
available on request.

Areas of Application
• Compression-proof rear insulating layer
for combined insulating constructions
e.g. with refractory concrete, lightweight
refractory bricks or ceramic fibres
• Front-side application up to 650°C
and high gas velocities, e.g. for high
temperature dryer, heat treatment
furnaces, hot-air ducts, etc.
• Heat shield for hot repairs, large-sized
covers, short-time even with tempera-
tures above classification temperature
• Precision and complicated cut sections
for dryer, household appliances, plant
and machine construction.
