These products combine the best possible sip plane and electrical insulation properties. Care is required during installation as they are not re-enforced and can tear on occasion.
Material such as GM40, MSM and SMS have the excellent slip plane and heat transfer characteristics of the pure mica laminates, combined with a strong glass reinforcing layer. This makes this material tear proof, better to handle and easy to install even in large furnaces.
These Combi Mica grades are most often used in furnaces melting iron
and aluminium. The provision of the insulation paper gives these materials
a range of insulating properties. This serves to reduce the power
consumption required to maintain a specific melt temperature. It also gives
the installer a way of controlling the thermal gradient across the refractory.
The Range is available in a choice of 1 mm, 2 mm or 3 mm (more upon
request) of bio-soluble insulation Paper or rockwool combined with Mica.
The compressibility of the insulation papers can help to absorb the thermal
expansion generated by the refractory crucible. More specifically in this range the CSML20SRP grade is reinforced internally with woven glass scrim cloth, which results in an exceptionally strong material.
