Bio soluble fibres

THERMOglaf materials belong to the product group of bio-soluble fibres. These materials are also called either AES (Alkaline Earth Silicate) fibres, HTGF (High Temperature Glass Fibre) or bio-soluble fibres. THERMOglaf materials have basically the same properties like THERMOfrax ceramic fibres except the extended range of classification temperature.

Because of the bio soluble characteristics these materials do not be classified as hazard substances. It is mandatory always to consider that these materials are not to be used at and below dew point ranges during furnace operation. Particularly in case of attacks of acid-aqueous solutions and in the presence of chemical reactions with Alkali etc. we strongly recommend evaluation of the application together with our material technology team.

THERMOglaf products made of bio-soluble fibres are characterized by high flexibility, very low thermal conductivity, low weight and low heat storage capacity. These fibres have an excellent themal shock resistance and are suitable for permanent high temperature use up to 1300°C. THERMOglaf products are available in different shapes and classification temperatures.

The following schedule presents a guidance of some THERMOglaf materials. In case of using our table the pre-selection from the large area can be arranged easily. In the download section you will find the specific material datasheets (MDS) of our products. Other materials are available on request. We are pleased to respond your message!

Group 1: Bio soluble fibre blankets

Our THERMOglaf-Blankets are needled on both sides with a limited shot content, a respectful tensile strength, a high degree of flexibility and an elastic recovery. The THERMOglaf-Blanket 120plus has a particular low shot content and excellent insulation properties. The blankets are completely inorganic products and do not develop any harmful vapor during initial heating-up. In case of wetting the fibers either with oil, water or steam, the thermal properties remain as originally after drying.THERMOglaf-Blankets can be easily cut and to be used for the preparation of high density bio soluble fibre modules. Our fiber products are the basis for energy-efficient refractory linings particularly high thermal resistant up to application temperatures of 1300°C.

Group 2: Bio soluble fibre modules

Our THERMOglaf-BLOCK modules are manufactured at our production located in Duisburg by using the bio soluble premium quality of THERMOglaf-Blankets. The modules are available in densities up to 190 kg/m3 and dimensions up to 600mm in length. The modules are made individually in terms of dimensions and anchoring system. In addition to standard module sizes our manufacturing is also prepared for wedge modules, bio soluble fibre modules with center anchoring and also with notches. Of course, corrosion and heat resistant anchor material will always be used.

Group 3: Bio soluble fibre boards & vacuum formed products

THERMOglaf-BOARD is a vacuum-formed ceramic fibre product. Because of the vacuum shaping technology various shapes can be produced. Along with different types of bio soluble fibres and different additive products the vacuum shaped fibres can be manufactured with a bulk density of 250 – 400 kg/m³ and classification temperatures from 800 to 1300°C. In addition, the surface of the bio soluble fiber vacuum shapes and boards can be provided with hardeners and coatings as required sometimes for special applications.

Group 4: Bio soluble fibre stripes

THERMOglaf-PACK are cut bio soluble fibre stripes. THERMOglaf packing stripes will be cut to the designed insulating thickness. The base material is THERMOglaf-BLANKET. These stripes usually with a common density of 130 kg/m³ are placed perpendicular to the hot flue gas direction and compacted during installation to bulk densities of 150-160 kg/m³. The fixed ceramic fiber packing stripes will be fastened mechanically either with THERMOfixx anchors or glued on expanded metal by using THERMOmixx-K 1300 adhesive. The surface of the vertically laid ceramic fiber packing stripes can additionally be coated with a special coating. This will increase the chemically resistance of the surface and the abrasion resistance required for hot flue gas velocities up to 30 m/s.

Group 5: Bio soluble fibre paper & felt

THERMOglaf-PAPER & FELT are bio soluble fibre papers and felts. Our bio soluble fibre papers & felts are made of washed bio soluble fibres and mixed with an organic binder. These products have good flexibility, are „free from crystals“, smooth and easy to install. Bio soluble fibre papers and felts are typically used for thin thermal insulations from 1mm to a maximum of 25mm.

Group 6: Bio soluble fibre ropes & packings

THERMOglaf-TEX are bio soluble fibre textiles such as bio soluble fibre ropes, bio soluble fibre packages or bio soluble fibre textures for high application temperatures. THERMOglaf textiles are extremely flexible and have excellent thermal insulation properties. These materials are not classified as hazard substances. Bio soluble fibre textiles consist of long fibres and an organic material supporting the matrix. Additionally, THERMOglaf-TEX fiber ropes and fibre packages are reinforced by either chrome wires or glass fibre. These products are ideally prepared for thermal sealings to be used for flanges.

Group 7: Bio soluble fibre joint and repair mastic

THERMOglaf-MASTIC materials are compounds developed for maintenance of bio soluble fibre furnace linings. THERMOglaf-Mastic is available either in buckets or in 330ml cartridges for easy filling of joints. The easy processing allows precise filling of joints and also maintenance of fibre surfaces. Some extremely stressed areas in the burner area can be protected with the material THERMOmixx C-1500 coating. An external dry-out is not required after partial repairs with this material.
