SINDANYO is WS H91 WS L23 high strength Insulation board sheet spacer rod manufactured machined part. Syndanio are non asbestos, non combustible High Temperature resistant Insulation Boards with High Electrical Insulation.


These boards are manufactured from high temperature resistant cement based products, reinforced with selected fibres. They have been specifically designed to provide excellent service under demanding thermal and electrical applications. This insulation board is a popular option when a high quality, strong and rigid material is required.


It is available in two different grades:

WS H91 : Commonly used as a high strength heat insulator.

WS L23 : Primarily used as an electrical insulator.


Syndanio Material Properties SINDANYO

· Temperature: up to +700°C (WSH91) & up to +230°C (WSL23).

· Easily machined.

· Strong and rigid.

· Excellent insulation properties.

· Low thermal conductivity.

· High strength at high temperatures.

· Suitable for machined components.

· Resistant to most acids and alkalis.


WSL23 is primarily used as an electrical insulator.

WSH91 is used more as a heat insulator.
