Bubble Alumina Tube Description
Bubble Alumina Tube offers excellent thermal insulation properties, enhanced by its unique cellular structure. It is well-suited for high-temperature structural applications that necessitate exceptional insulation capabilities and can withstand extreme temperatures. Furthermore, its pre-fired nature, absence of organics, and compatibility with various chemical environments make it a versatile choice for different industrial applications.
While Bubble Alumina exhibits a bulk density twice that of a premium -grade alumina fiber insulator, Bubble Alumina’s structure consists primarily of closed air-filled thin-walled cells which combine to give it exceptional hot strength and low thermal conductivity. This makes Bubble Alumina an effective high-temperature thermal insulator in structural applications where insulating capabilities cannot be sacrificed and appropriate for use at temperatures as high as 1825°C. It is pre-fired, contains no organics and exhibits high microwave and RF transparency. Its high alumina content makes it compatible with many extreme chemical environments.
