MICROTHERMOVERSTITCHED High temperature " exible microporous insulation panel Typical 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 speci" ed.
Petrochemical industry & power generation Piping insulation Back-up insulation in refractory lined pipes Rotary kiln insulation Hot pipe support insulation Exhaust systems Filler material for mattresses, cassettes, heat shields, expansion joints PFP (Passive Fire Protection)
Working & processing MICROTHERM (SEMI-)OVERSTITCHED can be shaped easily with a simple cutter (the procedure can be found on our website). The panels can be " xed in place with glue or by mechanical means such as anchors, pins and clips. For piping applications, the panels are installed with wire and straps, identical to conventional insulation materials (the procedure can be found on our website).
The MICROTHERM OVERSTITCHED and SEMI-OVERSTITCHED range of products are custom made " exible microporous insulation panels with very good thermal properties. The panels are produced in a glass cloth outer envelope, making them clean
& easy to handle. Stitching can be one-directional (2D " exure) for the MICROTHERM SEMI-OVERSTITCHED panels, or two-directional (3D " exure) for the MICROTHERM OVERSTITCHED panels. The formulation is an opaci" ed blend of " lament reinforced pyrogenic silica (alumina for 1200 grade).
MICROTHERM (SEMI-)OVERSTITCHED-1000R is a " exible, custom made insulation panel.
MICROTHERM (SEMI-)OVERSTITCHED-1000R HY is a " exible, 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.
MICROTHERM (SEMI-)OVERSTITCHED-1200 is a " exible, alumina based, custom made insulation panel which is capable of withstanding peak temperatures of 1200°C.
Properties & advantages Custom made + " exible Extremely low thermal conductivity High thermal stability Shock + vibration resistant Available in different temperature grades, including a hydrophobic version Non combustible Clean & easy to install (procedure can be found on our website)
Simple to cut & shape (procedure can be found on our website)
No harmful respirable " bres Environmentally friendly, free of organic binders Resistant to most chemicals Also available in HYDROPHOBIC 10
