Basalt fiber needle felt is made of a certain length of basalt short-cut yarn through a particular needle-punching production line, such as laying net needle-punching process, because the basalt fiber itself is an inorganic fiber, high-temperature working conditions, non-combustible. In contrast, basalt fiber has a natural environmental protection, acid, and alkali corrosion resistance environment, and other excellent performance and is widely used in high-temperature conditions of heat-insulating fire-retardant products.
