Calcium Silicate

800, 1000 & 1100

Calcium Silicate is a non-asbestos lightweight material available in sheet, pipe-section or machined formats. Having a low density, Calcium Silicate exhibits excellent thermal insulation properties together with good machinability and handling characteristics.

Its relatively low shrinkage makes it ideal for use as secondary or back-up insulation in high temperature applications such as furnace and launder linings. Similarly, it is well suited as an insulator in insulating lids and pipe supports.

Calcium Silicate is dusty by nature. To reduce dust, the material can be coated with a Sodium Silicate solution before using. When being machined, Calcium Silicate gives off large amounts of dust; suitable extraction equipment and protective clothing should be used.

Other benefits include:

  • Lightweight
  • Low thermal conductivity
  • Low shrinkage
  • Excellent machinability
  • Non-asbestos
