Kertherm is an insulation cover composed of hollow glass spheres, less than «mm in diameter. It looks like light grey powder but is very free-flowing. It contains no carbon. Keratherm has a bulk density of 0,4g/cm³ and a specific gravity of 0,77g/cm³. Keratherm melts at around 1250ºC, but the bubbles do not pop, and the insulation properties are retained well past the melting point. The coefficient of thermal conductivity is 0,09W/mk. Consequently a layer of Keratherm remains cool on top for a very long time. The use of Keratherm reduces sculling. Keratherm virtually eliminates radiant heat from the surface of a vessel, allowing operators to approach it closely without protection, making sampling and temperature measurement comfortable. Keratherm prevents gas pickup from the atmosphere.

Packaging: 7,5Kg polyethylene bags.
