High Temperature Thermal Insulation Materials

High Temperature Thermal Insulation Materials are featured with low thermal conductivity, low thermal capacity, low porosity, and low bulk density. So it is also called insulation refractory materials, and light weight refractory materials.

Why do we use high temperature thermal insulation materials?

The biggest problems of the thermal equipment is the serious heat loss, which wastes energy severely. Statistics show that different thermal equipment have different heat losses. Such as the steelmaking furnace the heat loss reach 8.5%, cement rotary kiln about13%, glass kiln15.7%, and the tunnel kiln of the refractory materials and ceramics reach up to about 37.8%. From the statistics above, we draw a conclusion that the energy utilization rate is lower than 33%.

Types of High Temperature Thermal Insulation Materials

High temperature insulation products can be classified into different materials according to different standards.

Based on the service temperature

  • High temperature thermal insulation products: More than 1200℃
  • Medium high temperature thermal insulation materials: From 600℃-1200℃
  • Low temp insulation materials: Do not belong to the high temperature thermal insulation products

At last, based on the application methods, some materials can be used directly close to fire, while the others can’t.

Due to the requirement of energy conservation, the rapid development of insulating refractory, and different factors that affect the insulation performance, such as the apparent and closed porosity, bulk density, as well as the true density, etc. No matter the suppliers or users should choose insulation materials scientifically. Only in this way can they save energy and reduce cost.
