The para flux®  product in the Lydech flux thermal and acoustical shields product family is designed to provide a marked temperature drop in high temperature applications. The dual metallic layer product has four functioning low emissivity surfaces, which lowers the IR heat flux. The metallic surfaces are decoupled by a layer of air, which dramatically lowers the composite’s thermal conductivity, while improving its recyclability, mass and cost.

General Performance

• Two metallic layer IR heat shield

• Low emissivity, parallel surfaces for high IR environments

• A heat flux reduction 1/3 greater than single layer shields

• High lateral thermal conductivity to spread heat away from hot zones

• Low vertical thermal conductivity (air) to increase the temperature drop across the shield

• Hemmed edges for handling safety and increased product robustness
