2Pcs High-Purity Alumina Foam Ceramic Furnace Plug Lightweight Thermal Insulation Plugs for Tube Furnace Quartz Tubes and Alumina Tubes, Length/50mm (Φ40mm)

Furnace plug diameter Φ18-117mm, length 50mm, suitable for tube furnace quartz tube use, the plug is made of 99% high purity alumina, with high temperature resistance performance, can be a long time in the high temperature environment of more than 1600 ℃ stable work. Specially designed for tube furnace plug tube structure, can accurately match different specifications of quartz tube and corundum tube, through the furnace plug to realize the sealing and insulation of both ends of the tube, to protect the stability of the constant temperature zone in the furnace. The porous structure of the foam ceramic is both breathable and airtight, which not only meets the needs of gas circulation inside the furnace, but also effectively blocks the intrusion of cold air from the outside. Foam plugs have excellent thermal shock resistance, are not easy to crack after repeated warming and cooling, and are chemically stable, porous honeycomb structure realizes the dual advantages of “light weight” and “strong thermal insulation”.
