Alumina fiber fabric is a type of textile material that is composed of alumina fibers. Alumina fibers are typically made from aluminum oxide (Al2O3) or precursor materials containing aluminum compounds. These fibers possess remarkable properties such as high-temperature resistance, chemical stability, and mechanical strength.
Application:
l Protection against metal splashes and sparks
l Thermal protection
l Thermal insulation of valves, flanges, turbines and boilers
l Thermal insulation of pipes
l Expansion joints
Advantage:
l Low heat conductivity coefficient and heat capacity,good performance against thermal shock;
l Outstanding electrical insulation under elevated temperatures with long lifespan;
l Outstanding ability against etching of nonferrous metals such as Aluminum and Zinc.
l Admirable strength under both low and high temperatures.
