Calcium silicate

Our calcium silicate-based technical composites contain no asbestos fibres, offer excellent thermal, electrical insulation properties and have low shrinkage.

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.

Main properties

• Low thermal conductivity
• Very good resistance to high temperatures
• Electrical insulation
• Low shrinkage
• Good resistance to compression
• Inflammable
• Inert material
• Easy-to-use

Packaging, subcontracting and storage

Products must be dry-stored. Dry in steriliser before use if the product has been stored for a long time.
