Flame retardanr
It has safe fire characteristics : Classification B1 Flame-retardant in accordance with DIN 4102, without addition of flameproofing agent.

Thermal resistant
Its high working temperatures and fire characteristics are attributable to the melamine resin employed. Basutai’s long-term service temperature gives it a leading position among the polymeric foams.
Its ability to withstand high temperatures (long-term service temperature approx. 200°C, and short-term peak temperatures of up to approx. 240°C are possible)

Thermal insulation
A further advantage is its low thermal conductivity . It is remarkable that this low value can be achieved with an open-cell foam. The reason for this is the reduced convection of the air due to the fine cellular structure of Basutai.

Chemical Stability and Resistance against microorganism
Due to its crosslinked molecular structure BASUTAI is very resistant to all organic solvents (hydrocarbons, alcohols, ketones, ester etc). BASUTAI is also resistant to weak and strong alkaline solutions.
BASUTAI is resistant against degradation by fungi and bacteria. The foam cannot be used as a carbon source by these organism.

Aftertreated
Basutai can be cut to shape by sawing and milling. The production of single boards can be achieved by means of a horizontal slitting machine. Complex geometries can be produced by means of contour or profile cutting.Laminated layers of felt, fabric, metal foil and plastic film can be applied. The hot pressprocess can equally be used to emboss decorative patterns on to ? boards.
