Alumina fiber Mat, a non-woven product crafted through spray and electrostatic spinning, yields a lightweight, organic-free material resistant to smoke or ignition at high temperatures. With a remarkable long-term serviceability up to 1500° C (max 1600° C), it retains resilience, strength, and flexibility in various atmospheres. Ranging from 0.2 to 1mm in thickness, the Mat excels in processability, finding significant market potential in high-temperature composite materials. Notable features include exceptional heat stability, minimal linear change, low slag content, superior fire resistance, and excellent thermal and mechanical properties. lts versatile applications span high-temperature tapes, resin/ceramic composites, aerospace thermal protection, fire isolation in battery casings, sound insulation, and high-temperature sealing and filtering materials.
