HYSIL Block

HYSIL. Insulation Blocks and Pipe Coverings are made from Hydrated Calcium Silicate reinforced with non-asbestos fibres. It is a rigid material with high compressive strength and low shrinkage at high temperature. … Longer life of 3 to 4 times the fibrous material due to high strength and resistance to vibrations.

HYSIL, a revolutionary brand in green industrial insulation, is a pre-formed, high temperature, abuse-resistant pipe and block insulation with exceptional structural strength. Composed of Hydrous Calcium Silicate (Calsil), it is designed for use on systems operating up to 1100°C.

Applications

Hysil Thermal Insulation Blocks

Also suitable for use in fire endurance applications, these are available in finish forms of the preformed block and preformed pipe. These are suitable for use in industry sectors like chemical plants, refineries, steam electric power plants and others.

Advantages

Reduced fuel cost due to low thermal conductivity and low thermal capacity. Consistent physio-thermal performance throughout its life. Longer life of 3 to 4 times the fibrous material due to high strength and resistance to vibrations. Economical as compared to conventional insulation.
