The Insulcon Group

Leader in high temperature solutions - Refractories, Wearflex Expansion Bellows, Refrex and Textile Products

  • Boards

    The product lines contains a wide range of (fibre) board products (f.e. Fiberfrax 120LD and ZK, Fiberfrax 140LD and ZK, Insulfrax 110LD and ZK, Isofrax 120LD and ZK and Millboards) which are specially designed for use in applications. Those product lines require high strength and rigidity coupled with high temperature stability and excellent insulating performance. This range encompasses a wide spectrum of operating temperatures and thickness combinations and is designed to meet the requirements demanded by today's industry.

     

    Typical applications are:

    * Rigid high temperature gaskets and seals

    * Furnace hot face linings

    * Refractory backup

    * Fire protection systems

    * High temperature baffles and muffles

    * Glass tank insulation

    * Hot gas duct linings

    Next to the range of standard products, other special board products are available on request.

     

    Insulfrax® board

    Insulfrax® Board products are manufactured from Insulfrax alkaline earth silicate wool blended with specially selected inorganic and organic binders to provide rigid boards with exceptional characteristics.

    110ZK is easy to cut and shape with standard tools. These boards exhibit high strength and rigidity coupled with excellent insulating performance and high temperature stability.

    110LD is particularly suited to applications where reduced out-gassing and/or high-definition mechanical machining are required. Insulfrax Board products are available in a wide range of sizes and thicknesses.

     

    Fiberfrax® Duraboard 

    The Fiberfrax Duraboard range has excellent chemical stability, resisting attack by most corrosive agents. Exceptions are hydrofluoric, phosphoric, hydrochloric and sulphuric acids as well as concentrated alkalis. Fiberfrax Duraboard products also resist oxidation and reduction

    Fiberfrax® Duraboard® 120LD is manufactured to tighter dimensional tolerances and have an excellent finished surface. These characteristics make them ideally suited for use as a sandwich or core material or for use in the manufacture of components where aesthetic quality, as well as uniformity and performance, is important.

    Fiberfrax® Duraboard® 120ZK insulation is a high-density board product that offers the same high level of dimensional and surface uniformity as Duraboard 120 (LD) insulation, but provides enhanced compressive strength and a higher modulus of rupture. This higher density is achieved through the inclusion of clay additives during the manufacturing process.

    Fiberfrax® Duraboard MD is a clay-filled board designed to meet the demanding requirements of modern industry. These boards exhibit high strength and rigidity coupled with excellent insulating performance and high temperature stability

    Fiberfrax® Duraboard® 140 insulation is a high-temperature insulating board designed to provide high stability at elevated temperatures. This capability is achieved by manufacturing a board formulated with a blend of Fiberfrax® alumina-silica fibres and Fibermax®, patented polycrystalline mullite fibres.

    Fiberfrax® Duraboard® 1500 is a board product that demonstrates excellent thermal stability (low shrinkage) at very high operating temperatures. Another benefit of these board products is their extremely high modulus of rupture (MOR) in both the green and fired state. Because of this strength, Duraboard 1500 is a very well-suited to applications where sag resistance is critical. 

    Fiberfrax® Duraboard® 1600 is, also as the Duraboard 1500 produced from a blend of Fiberfrax and high alumina polycrystalline fibres. This combination increases the continuous operating temperature capability, provides very low shrinkage at elevated temperatures, whilst maintaining excellent insulating properties. Duraboard 1500 has the same properties, only with the use temperature of 1600°C. 

     

    Isofrax® boards

    Isofrax® Board products are manufactured from Isofrax 1260C alkaline earth silicate wool, blended with specially selected inorganic and organic binders to provide rigid boards with exceptional characteristics.

    120ZK is easy to cut and shape with standard tools. These boards exhibit high strength and rigidity coupled with excellent insulating performance and high temperature stability.

    120LD is particularly suited to applications where reduced out-gassing and/or high-definition mechanical machining are required. Isofrax Board products are available in a wide range of sizes and thicknesses.

     

    Millboards 

    Millboards are a series of high density, rigid board products suitable for a variety of heat-resistant and industrial sealing applications. Millboards are available in a range of different formulations, each of which exhibits specific characteristics and physical properties.

    Millboards are also available in a selection of thicknesses. These rigid board products are manufactured to provide excellent performance in any application that requires high modulus of rupture (MOR) and a rigid form. The product is designed to resist erosion, vibration and mechanical stress, and can be easily customised on jobs to fit any installation.

    There are 4 type of Millboards: 

    Millboard 85K is based on a mineral wool / refractory ceramic fibre blend combined with selected fillers and is a commercial grade product suitable for applications with operating temperatures up to 850°C.

    Millboard 120K is based on refractory ceramic fibres and various fillers and is a general purpose millboard for applications with operating temperatures up to 1100°C.

    Millboard 85KB is manufactured from mineral wool fibres blended with clay fillers and is also suitable for applications with operating temperatures up to 850°C. The mineral wool fibres used are bio-soluble

    Millboard 120WT is a formulation based on wollastonite and is suitable for applications with operating temperatures up to 1100°C. This product is not classified under EU directive 97/69/EC.
