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.
