Fiberfrax® High Temperature Mastics

Insulation materials which produce a strong insulating structure with low thermal conductivity.

Fiberfrax Mastics are insulation materials which are composed of Fiberfrax refractory ceramic fibres dispersed in high temperature binders, which upon drying produce a strong insulating structure with low thermal conductivity. Fiberfrax Mouldable 160 contains both RCF and polycrystalline fibres, and High Temperature Mouldable contains only polycrystalline fibres.

These versatile products can be caulked, trowelled and/or moulded quickly and easily into place for use in filling, sealing, repair and general packing applications.
