A Choice Of High Quality Refractory Insulation Materials ----- Cenosphere

Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants.

The four major properties of high fire resistance, lightweight insulation and high strength, fine-grained large surface area are integrated, doubling the value of SEPPE cenospheres. No other lightweight insulation material can match this. It is not excessive to say that it is the king of insulation materials.
