Lukewool Bio-soluble Fiber Cloth is a high-temperature textile engineered from Alkaline Earth Silicate (AES) fibers. Unlike traditional ceramic fibers, these are designed with a chemical composition of CaO, MgO, and SiO? that allows them to dissolve in human body fluids if inhaled, making them a safer, non-biopersistent alternative for industrial insulation.
