Tag Archive Specialists for high-temperature applications

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.
