High temperature flexible microporous insulation panel

MICROTHERM OVERSTITCHED

FURMATS as authorized marketing partner of PROMAT offer their High temperature flexible microporous insulation panel. The MICROTHERM OVERSTITCHED and range of products are custom made flexible microporous insulation panels with very good thermal properties. The panels are produced in a glass cloth outer envelope, making them clean & easy to handle. MICROTHERM OVERSTITCHED is stitched in 2 directions for flexing. All versions are also available in a (SEMI-)OVERSTITCHED format which is primarily flexible in one direction. The formulation is an opacified blend of filament reinforced pyrogenic silica (alumina for 1200 grade).

MICROTHERM® OVERSTITCHED-1000X

is a flexible, custom made insulation panel.

 

MICROTHERM® OVERSTITCHED-1000X HY

is a flexible, custom made insulation panel with a hydrophobic core treatment to repel water. It is ideal for applications where contact with liquid water or condensation (dew point) is possible. Two hydrophobic grades available: hydrophobic (showerproof) for splash or rain resistance and full hydrophobic for more intense water resistance.

 

MICROTHERM® OVERSTITCHED-1200

is a flexible, alumina based, custom made insulation panel which is capable of withstanding peak temperatures of 1200°C

Typical applications

Microporous insulation ouers 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.
