More info

Boron Nitride Fiber is a high-performance ceramic fiber known for its exceptional thermal resistance (up to ~2000 °C), chemical stability, ablation resistance, excellent dielectric properties (dielectric constant ≤ 4.5, dielectric loss ≤ 5×10⁻³), and neutron absorption. These properties make it a valuable material in advanced fields such as aerospace, aviation, nuclear technology, and next-generation energy systems. We offer three product types: Flexible Boron Nitride Fiber Paper, which is used in 5G/6G communication insulation and thermal management devices, nuclear and railway electronics, and high-temperature insulation layers; Boron Nitride Fiber Cloth, ideal as a base material for aerospace components and high-temperature insulators; and Boron Nitride Fiber Felt, which serves as a substrate for wave-transparent materials and thermal insulation in ultra-high temperature environments. Heeger Materials provides high-quality Boron Nitride Fiber solutions to support demanding applications in cutting-edge industries.
