Handling Information

A Material Safety Data Sheet has been issued describing the health, safety and environmental properties of this product, identifying the potential hazards and giving advice on handling precautions and emergency procedures. This must be consulted and fully understood before handling, storage or use.

Isofoam™ & Foamfrax™ Products are monolithic insulation systems developed by Unifrax Corporation. Isofoam™ & Foamfrax™ Insulation are
three-component systems of specially conditioned bulk fibres, an inorganic binder, and an organic foaming binder.

The installation process mixes the bulk RCF or soluble fibre materials with the inorganic and organic binders in a patented mixing chamber. Within the mixing chamber, the fibres and binders are combined to create a homogeneous foam/fibre mixture. The specialist installation machinery
propels this mixture through a feed hose and nozzle, the material is then gunned onto the target surface. The proprietary binder system and patented installation method completely encapsulates the fibres with the foaming binder, significantly reducing airborne fibre levels during installation.

Isofoam™ & Foamfrax™ Insulation are easily installed at the job site by trained contractors using the special installation machinery. The interlocking network of fibres provides a strong, uniform monolithic structure having excellent thermal insulating properties, very low heat storage, and excellent resistance to thermal shock. Isofoam™ & Foamfrax™ Insulation is unaffected by most chemicals except hydrofluoric acid, phosphoric acid, and concentrated alkalies. Isofoam™ & Foamfrax™ Insulation are used to insulate metal, refractory (LOR) or ceramic fibre (FOF) surfaces at temperatures up to 1345oC. They can be installed at rates in excess of 2.5m3/hour and used in a wide range of furnace lining and other insulating applications. A principal application of Isofoam™ &
Foamfrax™ Insulation is to upgrade the efficiency of partially deteriorated furnace linings. The rapid application of a few centimetres of the specialist Insulation onto the existing hot face surface extends the furnace lining life and improves furnace efficiency. Isofoam™ & Foamfrax™ Insulation can also be installed as a full-thickness system by using stainless steel or ceramic anchors which are embedded within the Insulation to retain the furnace lining.
