Needled-puched felt provides very low thermal conductivity and can withstand continuous operating temperatures above -260/650, making it an adaptable material that ensures exceptional performance at high temperatures. With excellent versatility, better than ordinary fabric, it adapts to uneven surfaces to meet a variety of design requirements, while its chemical properties make it extremely durable and safe.
These outstanding properties make it widely used in some acoustic insulation systems, heat preservation, fire-resistant insulation, filtration and engine exhaust systems.
The noncombustible properties of basalt enable it to resist flames for long periods, making basalt felt effective as a high-strength insulator for electrical cables and underground pipelines.
