The international sewing thread producer Amann Group has launched a sewing thread made entirely from basalt stone fibers.

Known as Basalt tech, the thread can be used for a variety of different applications. It is ideally suited for protective workwear with maximum heat load, hot gas filtration, or applications with liquid metal contact. 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.

Basalt tech also 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.

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 per cent sustainable and plastic-free.
