Insulation Material Maximum Use Temperature Tester
The Maximum Service Temperature Tester for Thermal Insulation Materials is designed to evaluate the highest allowable service temperature of insulation products under controlled laboratory conditions. By applying a defined thermal load and monitoring material performance changes, the instrument determines whether an insulation material can maintain its functional properties during use or after exposure to high temperatures. This evaluation is critical for product design, quality control, and safety verification of insulation materials used in industrial, construction, and energy applications.
Applications
The tester is suitable for evaluating the maximum service temperature of a wide range of thermal insulation products, including:
Loose-fill thermal insulation materials
Mineral wool mats and blankets
Insulation felts and quilts
Rigid insulation blocks and boards
Preformed insulation pipe sections
Prefabricated mineral wool pipe shells
High-temperature insulation panels for industrial furnaces
Insulation materials for HVAC systems
Thermal insulation used in power plants and petrochemical facilities
