Sindanyo® H91 and L21 are portland cement based insulation materials that have been formulated to provide a long campaign life in demanding thermal and electrical applications, where high strength in a machined format is required.

Both products are asbestos free, have good insulation properties and are non-combustible.

H91 & L21 have low thermal conductivity which ensures consistent thermal performance.

Sindanyo® products have good compressive and mechanical strength which is retained when operating towards their maximum service temperatures.

Both grades also have very good impact resistance and toughness and can be easily cut, threaded and machined to make intricate parts.

Other benefits include:

• Asbestos free
• Resistant to most acids/alkalis
• Machinable
• Easily threaded or tapped
• Good wear resistance
• High compressive strength
• Electrically insulating
