Description
The RSLE-56 is flexible(formable), and is composed of silica reinforced ceramic fiber. It molds (shapes), and cuts easily. When dried it becomes a rigid structure. Further heat treatment or exposures to process temperatures significantly increase the physical strength of this material.
With a very low thermal expansion coefficient, combined with its high temperature strength gives it thermal shock resistance not found in other structural ceramic materials. This material also has a low thermal conductivity and is resistant to corrosion. It is an excellent electrical insulator, in addition to having a high chemical purity.
Applications
Molten non-ferrous alloys do not bond to the RSLE-56 making it useful in numerous molten metal contact applications. It can also be used in other applications such as : induction coil liners, glass furnace repairs, hot flue linings, hot press insulation, hot face insulation where gas velocity is of concern, casting tables and trough liners.
