Basalt fiber needle felt is made of basalt short-cut yarns of a specific length, processed through a specialized needle-punching production line, including processes such as web laying and needle-punching. As basalt fiber is an inorganic material, it is non-combustible and performs well in high-temperature working conditions. Additionally, basalt fiber offers excellent natural environmental protection, resistance to acid and alkali corrosion, and other outstanding properties, making it widely used in high-temperature applications as an insulating and fire-retardant product.
