1) high temperature resistance of ceramic fiber. The long-term use temperature can reach 850 ℃, and the composite process installation with other ceramic fiber products can reach 1300 ℃.

2) long service life. It can be used as a permanent layer of insulation, with a service life of 5-10 years.

3) economic and energy saving. It can save 10-30% energy than conventional materials.

4) environmental protection and non-toxic. It does not release any toxic substances in the fire and at high temperature, and does not contain asbestos (whole series), polybrominated biphenyls (flame retardants).

5) it has good chemical stability. It can withstand most of the acid-base environment except hydrofluoric acid and strong base for a long time, without decomposition and deterioration, and can withstand all kinds of thermal radiation (UV, infrared, visible light) and electromagnetic radiation for a long time, without degradation of performance.

6) sound insulation and shock absorption. The material is fiber material, which is an excellent sound insulation and shock absorption material. The sound speed in the material will drop to one third of that in the air.

7) excellent heat insulation performance. The lowest thermal conductivity is 0.015 w / m · K at room temperature (25 ℃), and 0.030 w / m · K at 600 ℃. Compared with the commonly used thermal insulation materials, the thermal insulation effect of the material can be increased by 2-10 times, and the thickness of the thermal insulation layer can be reduced by 30-50.
