The excellent thermal resistance properties exhibited by LTC HSA™ Systems are a result of the unique lightweight ceramic fiber paper core material composed of fine diameter fibers. This core paper has a small cell structure; in addition, all unfiberized particles have been eliminated. This results in very low thermal conductivity and superb high temperature insulation values. The high fiber index results in high resistance to mechanical and acoustical vibration. If wet by water or steam, all LTC HSA Systems thermal and physical properties are restored upon drying. It also exhibits excellent chemical stability and resistance to attack from most corrosive agents. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalies.
Providing very low thermal conductivity and superb high temperature insulation values, the recommended operating temperature of LTC HSA Systems is 1260°C (2300°F).
