Calcium silicate 220 is composed of inorganic siliceous and calcareous materials, treated through advanced high-temperature and high-pressure hydrothermal reactions. It offers exceptional performance at temperatures up to 650ºC and carries ISO9001 certification. A significant advantage is its superior protection for pipelines due to its extremely low chloride ion content. Continuous technical improvements have reduced thermal conductivity from 0.065 to 0.049.
