Fiberfrax® Mouldable Mastics

Fiberfrax® Mouldable Mastics consist of Fiberfrax ceramic fibres dispersed in a sticky, water-based refractory binder. These materials have a putty-like consistency, which permits application by caulking, trowelling or hand forming. Both products adhere well to most surfaces. Drying is accomplished at a non-critical, high temperature, and the resulting dried material is strong, hard and resistant to erosion.

Fiberfrax® Mouldable Mastics products also possess the advantages inherent to other Fiberfrax Specialties ceramic fibre insulating materials:

  • High temperature resistance
  • Excellent insulating properties
  • Thermal shock resistance
  • Chemical stability
  • Ease of installation

The Fiberfrax® Specialties range of products includes Fiberfrax mouldables, pumpables, caulks, coating cements, rigidisers, tamping mix and Moist-Pack blanket.
