Technical Advantages
Compared to traditional thermal insulation materials, basalt fiber needled felt contains no binders or adhesives. Consequently, it does not release harmful substances due to thermal effects during decomposition.
The starting material used for producing needled basalt fiber felt is basalt fiber with a monofilament diameter of 10-17µm. Compared to other materials (such as asbestos with a monofilament diameter of 1-3µm), basalt fiber mats are non-carcinogenic.
Basalt fiber needled felt does not shrink during assembly and processing, meaning there are no gaps between the insulation material and the insulated surface. Basalt fiber mats are easy to cut, making them simple to process. With an operating temperature range of -200°C to 650°C, the resistance of basalt fiber to corrosive media (such as acid and alkali solutions) provides an additional advantage.
