The calcium silicate fire-retardant sheet is formed from a mixture of tobermorite, xolotinite, and thermally stable minerals, which are synthesized under high temperature and pressure conditions. The material is micro porous, lightweight, resistant to high temperatures and heat, good sound insulation.
– Lightweight, porous microstructure should have good thermal insulation (low thermal conductivity) – High mechanical strength – High temperature resistance, can work stable at temperatures up to 1100 o C – absolutely no fire and no toxic smoke – no toxic substances for human health – no quality loss over time – easy to cut and process in the assembly process;
– White, easy to paint or apply various decorative coatings.
