The zetaflux® product in the Lydech flux product family is a multi-layer composite shield designed for application environments marked by aggressive vibration and noise generation.  The composite material is designed to damp the vibration response across a broad band of frequencies which reduces mechanical stress resulting from inertial forces and essentially eliminates parasitic noise generation.

Viscoelastic Layer

Low Temperature (LT)

• Tshield < 140 ° C

• Laminated Polyethylene

Mid Temperature (MT)

• Tshield < 220 ° C

• Co-Laminated Acrylic

High Temperature (HT)

• Tshield < 350 ° C

• Co-Laminated Silicon

Metallic Layers

• Aluminum 1050-O or 1100-O depending on the market

• Gauges from 0.1 mm to 1.0 mm are possible

• 2 x 0.3 mm is a common composite and consistently provides desired results

Thermal Performance

• Low emissivity surfaces for high infrared radiation environments

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

• The viscoelastic layer will provide a small reduction in cold side temperature

• High operating temperatures

Acoustical Performance

• High transmission loss for better acoustic isolation

• Marked vibration damping

• Essentially acoustically transparent – no contribution to noise levels

• No cooling ping

• No impact ring

Mechanical Performance

• Improved damping reduces the vibration response and transmissibility of the heat shield resulting in a decreased stress response due to inertial loading

General Performance Characteristics

• Resistance to all common automotive fluids 

• Non-inflammable composite per FMVSS 302

• Long-Term high temperature resistance

• No delamination
