TECH Telisol 5.0 QN is the special thermal insulation solution designed to meet the tough requirements of the nuclear power industry for insulation inside the nuclear island. It can be used for insulation of the heat exchanger and steam pipes. 

TECH Telisol 5.0 QN provides premium thermal insulation and keeps its performance long-term even when exposed to mechanical stress due to an elastic fiber structure. TECH Telisol is almost free of organic content, does not contain corrosion-supportive ions and is stitched with a yarn on austenitic stainless wire mesh to allow flexible bending. When upheated, the product can expand and fill possible gaps and joints.

Key Benefits

  • Nuclear plant quality
