PYROBOARD 55 is a newly developed rigid high-strength 99.7% SiO2 matrix. It can be considered a real substitute of Sindanyo CS51 at high temperatures.
Engineered and produced with low expansion raw material, PYROBOARD 55 exhibits greater thermal shock resistance than alumina matrix composites and high temperature calcium silicate matrix materials. It retains 96% of original strength throughout 1000°C, it is 100% inorganic and undergoes little or no outgassing on heating.
