Description
This silica reinforced composite is in a cylindrical form. It has outstanding resistance due to its high endurance. Since it has a very low coefficient of expansion, this material offers superior resistance to thermal shock in an oxidized atmosphere.
Applications
The RSLE-501 was designed for use as durable insulators in induction heat treating applications. It is also used in zones where temperatures may rapidly.
