Leadsun ceramic fiber paper is produced from high-purity alumina-silica fibers and processed into a flexible, lightweight refractory sheet. The material exhibits low thermal conductivity, low shrinkage, and excellent workability. A controlled amount of organic binder improves flexibility while reducing off-gassing and odor during operation. Uniform thickness and density ensure homogeneous thermal performance and a smooth surface, making it ideal for sealing and gasket applications.
