In this video, we take a close look at the High Alumina Ceramic Fiber Blanket, a needled insulation roll engineered for reheat furnaces and high-temperature refractory linings. You'll see how its elevated alumina content (52–55% Al₂O₃) delivers a 1400°C classification temperature and continuous service up to 1200°C, and we demonstrate its thermal shock resistance, chemical stability, and non-combustible performance. We also walk through key technical parameters, typical applications in metallurgical, ceramic, and glass industries, and how the needled structure holds fibers together for a durable lining. Ideal for B2B viewers evaluating extreme-heat insulation solutions.
