Fiberfrax^® and High‑Temperature Mastics

Fiberfrax^® Mastics are insulation materials 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
