Sindanyo® H91 Bar

Sindanyo® H91 Bar is a rigid engineering cement based on a high-strength, asbestos-free formulation designed for thermal insulation and electrical isolation in hot, demanding assemblies. As a bar stock it machines cleanly, holds drilled and tapped features, and keeps edges intact through heat-up and cool-down, so fixtures and spacers remain tidy under clamp load. Core advantages include dependable strength at elevated temperature, stable dielectric behavior at service heat, and low shrink during thermal excursions—traits that help designs maintain clearances and surface quality next to heaters and exhaust paths. Foundries, kiln and furnace builders, and power-equipment makers rely on it for jigs, standoffs, and pressure-spreading blocks around doors, ports, and burner hardware. Typical uses include insulating bars for coil and element supports, heat-shield rails that protect adjacent components, and structural shims in test rigs. For research and production teams, H91 bar provides a practical, machinable alternative to fragile refractories, enabling robust thermal barriers that assemble quickly and last.
