tesa® 54718 Noise Blocker Adaptable

Sound attenuating hole covering solution with extended cloth top layer



Product description

tesa® 54718 is a thick mineral filled polyolefin with an extended cloth top layer with high adhesive power to cover unused holes in the car body that require acoustic isolation, temperature resistance and secure mounting even on difficult to reach application areas. The extended top layer offers good UBC and paint compatibility and supports an easy and secure application even for holes in recessed or raised areas.

Features:

  • High area density ≥ 1.8kg/m²
  • Significantly reduce and absorb noise regardless of the hole size to enhance the acoustic comfort while driving
  • Extended cloth top layer ensures an excellent seal and ageing resistance and suitability to UBC and painting processes up to 160°C

Main applications

tesa® 54718 is especially designed for permanent hole covering applications in the paint shop or at the assembly line to significantly reduce the noise level within the passenger compartment caused by open holes in the car body. The acoustic damping performance achieved is comparable with a closed car body.
