Understanding Ceramic Fiber Blankets
Ceramic fiber blankets are made from high-quality refractory ceramic fibers, primarily composed of alumina (Al2O3) and silica (SiO2). These materials are melted down and spun into fibers, which are then needled together to create a flexible and durable blanket. The needling process enhances the fiber’s interlocking capabilities, providing superior strength and thermal resistance.
