Material & Characteristics

95% Alumina Ceramic Beads from HeatMent™ is manufactured by dry press method and is sintered at temperature upto 1650°C. All the material is prepared by "RESISTEK", parent company of HeatMent™, even from the very first material.The production is under careful material selection of high grade alumina spray drying granulation from what we call calcined alumina, 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 operation of pre- and post-weld heat treatment, welding process, stress-relieving, ship-building, other heat-resistance-environment.
