| Application areas | Protection and Insulating Tubes Protection and insulating tubes made from technical ceramics are the first choice in temperature and measurement control situations, whenever safety and stability aspects are required. Ceramic protection tubes and insulating tubes from CeramTec are used in manufacturing devices for temperature measurement and control. Their resistance against aggressive atmospheres even in the most demanding conditions, where temperatures reach up to 1,700°C make CeramTec products the first choice. The various CeramTec alumina ceramics used, such as Rubalit® C799 or Dimulit® C610, are characterized by their excellent electrical insulation and high mechanical strength. CeramTec also offers a slightly porous material Pormulit® C530. CeramTec protection and insulating tubes are manufactured in accordance to DIN 40680 standards. | |
