Sindanyo® H91 Sheet

Sindanyo® H91 Sheet is a rigid, asbestos‑free engineering cement board designed for thermal insulation and electrical isolation in hot, demanding assemblies. It machines to clean edges and holds shape during heat‑up and cool‑down, making it a practical choice for jigs, fixtures, and structural barriers around heaters and furnaces. Furnace and kiln builders use it for door surrounds, sight‑port shields, and burner blocks, while test equipment and power hardware rely on it for insulating spacers and panels. The sheet’s balanced strength and low density support easy handling and fastening without crumbling, and its surface takes adhesives and sealants well. In service, it helps reduce heat loss and shields adjacent components from hot spots, contributing to safer equipment and more stable process control. For production and research setups, Sindanyo H91 simplifies builds that need robust, repeatable insulation without the brittleness or fragility of traditional refractory solutions.
