Acoustic systems for underbody protection and sealing with integrated sound insulation properties for car automotive market

Sound damping
We offer different systems for optimum sound damping, they ensure the optimization of cost, weight and acoustic properties of the construction of cars and vehicles. The range includes impact-resistant coatings that are pumpable, expanding and vibration dampening, ideal for vibration damping, and are used for example for doors and gland plates with corrosion-resistant properties. We also offer self-adhesive, multilayered systems that are ideal for manual applications and are available in many forms. Multilayer systems absorb the vibration energy of the components to which they are applied.

DECI-TEX Acoustic Soundproofing
The fiber-based L&L DECI-TEX acoustic technology is developed and tailored mainly for customer-specific applications. The advantage of the DECI-TEX product range compared to its competitors is the excellent acoustic and thermal efficiency combined with reduced weight and reduced material consumption. The elasticity of the vertical fiber construction leads to first-class mechanical integrity compared to other nonwoven insulation and prevents condensation, whereby the acoustic effect is still permanent.
