MICROTHERM OVERSTITCHED

MICROTHERM OVERSTITCHED

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.
