High-Temperature Textiles & Textile Seals

The portfolio includes high-temperature and fiberglass tapes, braided packings, sealing cords, textile sleeves and custom-made sealing profiles. Depending on the product group, different fiber materials, dimensions and constructions are available.

Depending on the requirements, textile high-temperature products are made from materials including E-glass fiber, HR glass fiber, silica glass fiber, biosoluble AES fiber and ceramic fiber. The materials differ particularly in their temperature ranges and application-specific properties.

E-glass is a proven material for numerous technical textiles in the moderate temperature range. HR glass grades are designed for increased thermal requirements and therefore extend the application range of conventional fiberglass textiles.

The suitable material depends not only on temperature but also on the product construction and operating conditions.

Silica fibers have a high SiO₂ content and are used particularly for higher thermal loads where conventional fiberglass grades reach the limits of their suitable application range.

Whether a silica product is required should be evaluated on the basis of continuous and peak temperature as well as the specific thermal exposure.

AES stands for Alkaline Earth Silicate. These are biosoluble high-temperature fibers used for various flexible sealing and insulation products. Depending on the construction, products such as tapes, cords and packings are available.

Depending on the fiber material and product construction, textile solutions are available for different high-temperature ranges up to approximately 1,260 °C.

However, the maximum temperature of a fiber material must not be applied indiscriminately to every product manufactured from it. Reinforcements, coatings, yarn construction, and the duration and type of thermal exposure can affect the actual operating range.

Sealing cords are flexible textile products that can, for example, be twisted, knitted or braided. Packings typically have a defined braided construction and are available in different cross-sections such as round, square or rectangular.

The more suitable design depends on the sealing gap, compression, geometry and mechanical load.

Selected tape grades are available with a self-adhesive backing as an installation aid. It is important to note that the temperature resistance of the adhesive system must not be equated with the temperature resistance of the high-temperature textile.

Availability and suitability are therefore evaluated for the specific application.

Tadpole gaskets combine a flexible textile sealing bulb with a mounting tail. This allows the profile to be secured to the component while the bulb provides the actual sealing or insulation function.

They are particularly suitable for custom sealing geometries in machinery, plant and furnace engineering.

Particularly helpful information includes product form, dimensions, continuous and peak temperature, installation situation, required function, mechanical load and required quantity.

For custom profiles or special designs, drawings, photos or existing samples facilitate technical evaluation.
