Decidamp CLD PRO is a constrained layer, visco-elastic damping material, designed to reduce structural vibration and sound transmission within light gauge materials. Decidamp CLD PRO was developed to meet market noise reduction requirements in the automotive, industrial and OEM markets.
To achieve this high-performance, the Pyrotek engineering team developed a product that thermally bonds two layers; a rigid outer metal layer and a visco-elastic adhesive membrane, hence the name CLD (Constrained Layer Damping).
Vibration is reduced due to the introduction of shear forces between the substrate and the constraining layer on Decidamp CLD PRO. These shear forces convert vibrational energy to heat, resulting in a damping effect.
Lightweight panel constructions such as sheet metal (steel, alloy, tin etc.) and rigid plastics (ABS and FRP etc.) can easily transmit noise when vibrational energy is introduced to the structure.
By applying Decidamp CLD PRO to lightweight structures, the damping of the construction will increase, therefore lowering radiated noise (vibration) and improving the transmission loss.
