PROMAPACK boards are rigid insulating materials based on mineral wool, wollastonite, and aluminium silicate wool with mineral filling components. The boards are bound with both organic and inorganic binders. Due to this combination, the boards have high temperature resistance, low thermal conductivity and good electrical insulating properties. This material is asbestos-free and with its all-round properties it replaces previously used

asbestos boards. The areas of application are numerous and not limited to the main application field of high temperature seals.

​

PROMAPACK can be punched, cut, milled and drilled easily with conventional woodworking machinery with hard-metaltipped tools. PROMAPACK boards have the additional advantage that they can be shaped in wet condition without breakage.

​

Advantages​

• High mechanical strength

• Thin, lightweight and rigid

• Smooth surface

• Can be shaped in wet condition

• Excellent machinability

• High temperature resistance

• Insensitive to thermal shocks

• High electrical insulation

• Low thermal conductivity

• Hardly wetted by molten metal

• Good acid resistance

 

Applications​​

• Heat protection

• As insulating and sealing material, especially as a substitute for previously used asbestos boards.

• High temperature sealings

• Carrier material for roller conveyors in metallurgy and in the glass industry

• Rear insulating layer in furnace construction as a barrier layer and for absorption of aggressive condensates

• Household appliances, heating systems and burners

• Protecting device and welding pad
