Decidamp® CLD is a constrained layer, viscoelastic damping material, designed to reduce structural vibration and sound transmission within light gauge materials. CLD was developed to meet market noise reduction requirements in the automotive, marine, industrial and OEM markets.
Performance
To achieve this high-performance, the Pyrotek engineering team developed a product that thermally bonds three layers: a rigid outer metal layer, a viscoelastic membrane and a high-tack adhesive layer, hence the name CLD (Constrained Layer Damping).
The product achieves the highest fire rating, complying with International Marine Organization standards for low spread of flame, as well as British standards, achieving Class “O”.
Vibration is reduced by allowing the viscoelastic layer to flex, which creates shear strains between two rigid substrates, hence noise-creating energy is lost.
Applications
Most effective when applied to lightweight panels and steel substrates of up to 2 mm, aluminum substrates up to 4 mm and FRP (solid) up to 6 mm thick
Automotive floors, firewalls, doors, ceiling and trunk panels
