high temperature
microporous insulation

STEELFLEX

FURMATS as authorized marketing partner of PROMAT offer their high temperature microporous insulation, we offer STEELFLEX panels which are specially designed for steel industry & other hot metal applications. The flexible microporous insulation panels have very good thermal and mechanical properties. The formulation is an opacified blend of filament reinforced pyrogenic silica (alumina for 1200 grade). The product range consists of three temperature grades, all available in different covering types. All coverings are water repellent to ensure the stability of the microporous core when moisture might occur due to castables, mortar, …

applications

Microporous insulation offers an extremely low thermal conductivity, close to the lowest theoretically possible at high temperatures. Microporous materials are the preferred choice when a large temperature reduction is required within a limited space, or when strict heat loss or surface temperature requirements are specified.
