Basalt fibre sleeve

Made from basalt fibres of 8 to 16 μm, the felts are classified M0 according to European standard EN 13-501-1. They do not burn, do not melt, produce neither smoke nor toxic gases, and are environmentally friendly and recyclable. They are mainly used as electrical and thermal insulators.

Manufactured from 8-16 μm basalt fibres, the sheaths are mainly used in the automotive industry or for electro-mechanical applications. They have thermal and mechanical properties superior to those of fibreglass and can be used in the manufacture of composites. They are also used in the insulation of electrical cables and as thermal protection for pipes and exhausts.
