If used for the production of sewing threads, basalt offers special characteristics that are beneficial for a variety of different applications. As Basalt-tech withstands even highest temperatures, it is ideally suited for protective workwear with maximum heat load, hot gas filtration, or applications with liquid metal contact. Therefore, Basalt-tech is an ideal choice, where aramide threads reach their limit in terms of temperature resistance. Its burning behavior got tested by Hohenstein Laboratories according to DIN EN ISO 15025. Thanks to its special raw material, the permanent temperature resistance of Basalt-tech is up to approx. 650°C and the softening temperature at approx. 1050°C.

On top, Basal-tech combines the most diverse features in one thread: it resists chemicals, corrosion, rot and UV and can be used for e.g. thermal covers. Another unique benefit of Basalt-tech is its non-conductivity. This special feature is very important for e.g. sleeves for welding equipment to protect electronics.

Last but not least, Basalt-tech can also be used in hydraulic engineering. Basalt bags filled with sand, gravel or concrete from Jaeger Mare Solutions GmbH are used, for example, as scour protection around wind power plants, as cable weights for submarine cables or in the area of dyke stabilisation. These bags are made of basalt fabric and sewn with the Basalt-tech sewing thread. This makes the entire application 100% sustainable and plastic-free.
