The alumina ceramic beads from HeatMent™ is manufactured by dry press method and is sintered at temperature upto 1650°C. The production is under careful selection of high grade alumina (95% Al2O3) by “RESISTEK”, a sister company of HeatMent™, thus the stability is maximumly ensured. It enjoys high temperature resistance, excellent insulating property, and efficient thermal conductivity and heat transfer.
Thanks to its excellent characteristics, the ceramic beads is widely used as components of ceramic heating pad at operations of pre and post weld heat treatment, welding process, stress-relieving, ship-building, other heat-resistance-environment.
