MYREAL calcium silicate 220 is taking inorganic siliceous and calcareous as material and treated by special technology such as high temperature and high-pressure hydrothermal reaction, and the product has won ISO9001 certification. It has excellent performance under the temperature of 650ºC. The greatest advantage is it can provide nice protection to pipelines since it with super-low chloride ion content. Thanks to the improvement of producing technology, we have reduced the thermal conductivity from 0.065 to 0.049 at present.
