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.
