Properties: High density, good apprearance and high alumina content, excellent thermal condictivity and heat transfer, resistance against thermal shock and mechanical abuse.
Application:This special sintered alumina ceramic beads as components of ceramic pad and channel heaters can be used for pre and post-heaters welding applications because of its excellent heat resistance.
All flexible ceramic pad heaters are constructed of 80/20 Nickel/Chrome multi-strand wire, insulated with interlocking sintered alumina pink ceramic beads, nickel cold tail wire, and two Male Camlocks.
