Calcium silicate composite

Calcium silicate machinable thermal insulation

Overview: Calcium Silicate Composite

Calcium silicate is a powder with the formula Ca2SiO4. This technical composite is primarily employed for its excellent high-temperature properties. 

Calcium silicate is a low-density material, white in colour. It is odourless and poses no known health risks. Its derivatives are highly valued for their low thermal conductivity, their high resistance to heat and their limited dimensional shrinkage.

Implementation

Calcium silicate composites can be sawn, bevelled, drilled, screwed and machined with traditional machines, tools and techniques

For cutting and processing, tools with hard metal tips must be used. The cutting equipment must include a dust extraction system.
