Textile for high temperatures

The trading and consulting company Kager has expanded its selection of special textiles for high-temperature applications with additional semi-finished fiber fabric products. The focus is on flexible mats and tapes made from E-glass fiber and silicate fiber fabrics. They are made of smooth or textured yarns and are available in different weaves. Their main area of ​​application is protection against high thermal loads.

When it comes to tasks in high-temperature technology, the trading and consulting company Kager is one of the first addresses in the country for many device and apparatus manufacturers. In its ever-growing range of special and niche products for sealing, bonding and insulating, optimal solutions to problems can be found for many thermally sensitive applications. It has now added several semi-finished products made from E-glass and silicate fiber fabrics to its selection of heat-resistant textiles. They are one of those special textiles that are used in industry and trade to protect people, machines and other materials from high thermal stress. Depending on the specific task, they can therefore take on functions of product protection and quality assurance as well as serve occupational safety. Given the wide range of applications, Kager primarily offers them as mats and tapes in which smooth or textured yarns are woven in various weaves.

How hot can it get? The new high-temp semi-finished products in the Kager portfolio have different surface coatings and are suitable for environments with temperatures of up to 1,300° C. The customer can choose between six E-glass fiber variants and a silicate fiber fabric. In addition to its resistance to high temperatures, the advantages of organic E-glass fiber include its ability to provide electrical insulation. The silicate fiber, on the other hand, consists of inorganic substances, does not contain any toxic components and is often an alternative to ceramic fiber products due to its very high thermal (and mechanical) strength. A look at the new selection of E-glass fiber fabrics shows that the different degrees of temperature resistance of the individual variants are primarily due to the type of coating. Coated on both sides with food-grade silicone, the E-glass fiber fabric, for example, achieves a temperature resistance of up to 400° C, while with a non-flammable vermiculite coating on both sides it is suitable for short-term resistance up to 1,300° C. Kager also offers a version with a gray Alufix coating (up to 1,000° C) and a version with a flame-retardant, graphitized high-temperature coating (up to 750° C), which is characterized by high resistance to sliding and cutting. The silicate fabric semi-finished products also have a vermiculite coating (up to 1,300° C).

How tight does it have to be? All of the new high-temp fabrics in the Kager range consist of either plain yarn or textured yarn. Another similarity is that the customer can choose between three different types of weave: the high-strength, extremely dense satin weave or the distortion-resistant, closed plain weave or the cross-body weave, which scores above all with its insulating air storage and excellent dimensional stability. The high-temperature fiber fabrics newly added to the Kager range are high-quality products. Their technical values ​​almost always correspond to the relevant DIN standards and have been confirmed by the Dresden Materials Testing Institute (MPA). To ensure that the customer always receives the right solution to the problem with the most suitable coating, the optimal yarn quality and the ideal type of weave, Kager has competent consultants available to talk to.

The Kager-Team wishes you a Merry Christmas

Another year is coming to an end. Unfortunately, things did not get any better compared to last year. On the contrary – the war in Ukraine continues, and now there is also the conflict in the Middle East, not to mention other trouble spots around the world. Only Corona has faded into the background. There remain high costs in almost all areas, which burden private households and companies. When we put all of this together, it becomes even more difficult to be optimistic. We cannot change many of the aforementioned topics at all or only to a limited extent.

Let us still try to look at the beautiful things in life and focus on them. These are experiences in our own environment that can bring you joy. It can be conversations that have nothing to do with current topcis or activities that fill you with joy. It is up to us to make the best of the current sutiation. There is a nice sentence from Nikolaus B. Enkelmann .

„Attention brings reinforcement, ignoring brings liberation!“

We would like to give you a little encouragement for the year 2024.

The Kager team wishes you all a Merry Christmas and a good and, above all, healthy start to 2024!

We would be happy to continue to be available to you next year as specialists for high-temperature applications.

Insulation in e-mobility with ceramic fiber paper

The use of ceramic fiber paper in electromobility encompasses several applications owing to its insulating, heat-resistant, and lightweight properties. Here are some potential applications:

  1. Insulation of Batteries and Electric Motors:
    • Ceramic fiber paper is often employed as thermal insulation for batteries and electric motors in electric vehicles. Its high temperature resistance helps stabilize operating temperatures and prevent overheating.
  2. Thermal Shielding:
    • Electromobility components such as batteries and electric drives generate significant heat. Ceramic fiber paper can serve as thermal shielding to keep heat away from sensitive electronic components, enhancing efficiency and extending the lifespan of these components.
  3. Lightweight Construction:
    • Due to its lightweight nature, ceramic fiber paper contributes to reducing the overall weight of electric vehicles. This is crucial for optimizing vehicle range and improving overall efficiency.
  4. Thermal Management Solutions:
    • Ceramic fiber paper can be incorporated into thermal management solutions to efficiently dissipate and distribute heat. Ensuring uniform temperature distribution across various vehicle components is critical for optimal performance.
  5. Fire Protection:
    • With its excellent fire-retardant properties, ceramic fiber paper enhances safety in electromobility by slowing down the spread of fire and minimizing potential damages.

It is important to note that the specific applications of ceramic fiber paper in electromobility depend on the unique requirements and design decisions of individual vehicle manufacturers. Consequently, the precise use cases may vary based on specific needs and design considerations.

Technical ceramics made of pyrophyllite stone for the production of prototypes and small series

Ceramic made from pyrophyllite stone involves utilizing pyrophyllite minerals in the production process. Pyrophyllite is a naturally occurring mineral classified within the group of layer silicates. It consists of aluminum silicate and lacks iron or titanium impurities. Pyrophyllite possesses a distinctive crystalline structure, rendering it suitable for crafting ceramic products.

The production of ceramic from pyrophyllite stone typically involves the following steps:

  1. Raw Material Extraction: Pyrophyllite is extracted from mines where it occurs in the form of mineral blocks or powder.
  2. Crushing and Processing: The obtained raw material is crushed and ground into a fine powder.
  3. Shaping: The powder is mixed with water to form a moldable mass, which is then shaped into the desired form using methods such as casting, pressing, or others.
  4. Drying: The shaped ceramic pieces are carefully dried to remove excess moisture and prevent cracking.
  5. Firing: The dried ceramic pieces are subjected to high temperatures during the firing process. The specific temperature depends on the type of ceramic and desired properties. During firing, the pyrophyllite particles fuse together, creating a solid ceramic structure.
  6. Glazing (Optional): After firing, the ceramic may be coated with a glaze to seal it and provide a shiny finish.

Ceramic made from pyrophyllite stone can have various applications based on its composition and firing temperature. These applications range from decorative art objects and tableware to technical ceramic products. Pyrophyllite ceramics often exhibit high heat resistance and low thermal expansion, making them useful in applications such as furnace linings, insulators, and other high-temperature uses.

Kager supplies technical ceramics type 9020 for industry in the form of plates, discs and rods. Ideal material for prototyping and small series. The trading and consulting company Kager also offers the service of custom-made products according to technical drawings.
