High Temperature Basalt Felts 700°C

Basalt Felts, up to 700 °C

Basalt fibre has properties that are far superior to fibreglass. For example, basalt fabric subjected to the flame of a Bunsen burner will redden and could withstand for several hours compared to a few seconds for a fibreglass fabric of the same density. In addition, basalt fibre is the most environmentally friendly high temperature resistant material when it comes to both manufacturing and recycling it.

Basalt fibre products resist well to fire and chemical agents. Because basalt remains functional from -260 °C to 700 °C, it can be used for high temperature as well as cryogenic applications. 

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. They are mainly used as electrical and thermal insulators.

Applications of Basalt Felts

• Insulation of exhaust
• Electrical and thermal insulation
• High temperature and cryogenic applications
