The iso flux® product in the Lydech flux thermal and acoustical shields product family is  a  thermal  encapsulation  that  serves  to  protect sensitive components from heat radiated by the exhaust line and maintains thermal calories in the exhaust line to facilitate catalyzation and filtration processes.  A low thermal conductivity fiber is placed in direct contact with the exhaust line component and is covered with thin metal layer.

Metallic Layers

(i) Stainless Steel

• Austenitic and Ferritic grades based on temperature, environmental and economic constraints.

• Flat or embossed

• Shield Tmax < 1000 °C

(s) Aluminized Steel

• Various aluminized coating weights as a function of environmental/corrosion resistance requirements

• Flat or embossed

• Shield Tmax < 500 °C

(a) Aluminum

• Flat or embossed

• Shield Tmax < 300 °C

Thermal Performance

• Low emissivity surfaces for high IR environments

• Low thermal conductivity media in contact with the exhaust component

• Combined functions: thermal shielding and isolation

• Homogenous temperature distribution in exhaust component

Acoustical Performance

• Decoupling of exhaust component with the engine compartment

• Marked noise absorption

• Higher transmission loss for better acoustic isolation

• Option to pierce/perforate the metallic layer to increase the effective noise absorption area

Mechanical Performance

• Hemmed edges for handling safety and increased product robustness

• Roll and plate embossment provides an increase in part rigidity and improves formability

• Wide array of approved and commonly used alloys available to exceed the requirements of harsh thermal and mechanical environments

Assembly

• In-house: hemming, spot welding or mechanical fasteners

• Delivered ready to assemble – through similar or customer specific methods
