RCF Free Tapping

ISOTAP(Dry)/F tamp (Wet)

ISOTAP（Dry）and F TAMP (Wet) are heat insulating castable consisting of refractory fibers and refractory grains.

ISOTAP is lighter and more effective in heat insulation
than ordinary castable refractory and plastic refractory.
Used as lining material,
because of its good adhering property,
to the industrial heaters
where hard to install High Temperature Insulation Wool products.

ISOTAP can be installed easily and made into various shapes
Suitable to daubing and tapping installation.
ISOTAP F-12A and F-14A are dry type and hydraulic setting materials.
Mixed with water and becoming hard.
like ordinary castable refractory in room temperature
They are lighter and better in heat insulation
than ordinary castable refractories.
They have high strength.
in spite of their major constituent of High Temperature Insulation Wool.
ISOTAP has high volume stability at drying and heating.
The fibrous material contained in these products is
exempt from the German Technical Rules for Hazardous Substances (TRGS 905)

F TAMP is wet type heat insulating castable.

Typical Applications

Skid pipe insulation of reheating furnace
Hot air duct insulation
Other general heat insulation
