95type-M Polycrystalline Alumina Fibre
95-M type polycrystalline alumina fibre is widely used as high-temperature filter material and catalyst carrier in the field of catalytic combustion and environmental protection waste gas treatment.
Product introduction

95-M type polycrystalline alumina fibre is made with 95% Al2O3 and 5% SiO2 as the main components by the internationally leading "sol gel" method. This fibre has the characteristics of high fibre activity, fine fibre diameter and high specific surface area.


  • Excellent quality
  • Low cost
  • Good performance
Product performance

Excellent high and low temperature resistance

α- The service temperature of Al2O3 Fibre is up to 1400℃-1800℃; After treatment with liquid nitrogen (- 196℃) for 24 hours, the strength did not decrease.


Acid and alkali resistance

Retention rate of fibre strength after soaking in 10% alkali solution for 24h: NaOH -- 40%; KOH--65%; NH4OH--95%; The fibre strength retention rate after soaking in 10% acid solution for 24h: HCl-96%; H2SO4--95%;  HNO3--96%;  H3PO4--95%。


Slag free ball

Our fibre are shot free (≥ 45 μ m), the fibre strength has been improved to a certain extent. At the same time, because the thermal insulation and fire resistance of the fiber are inversely proportional to the shot content, the lower the shot content, the higher the thermal insulation and fire resistance.


Excellent electrical insulation

The resistance of alumina fibre decreases with the increase of temperature. Above 600℃, the resistance tends to be constant. The dielectric constant and dielectric loss of alumina fibre are basically stable at high temperature and are suitable for high temperature wave transmission materials.


Excellent flexibility

Good flexibility: the fibre has high flexibility and is not easy to break in the process of acupuncture. It is a very suitable product for acupuncture.


Strong design

By adjusting chemical composition and heat treatment process, products with different properties can be obtained to meet different application needs.
