Product information STP Bromo - Multilayer insulation mat for noise reduction

The new STP Multilayer Bromo is a highly effective material for reducing noise in vehicles.
Ideal for high-quality audio installations and significantly reducing driving noise and road noise.

Structure of the multilayer mat:

•  soft deck sends
•  Sound-absorbing heavy layer
•  Sound-absorbing layer made of foam
• Adhesive layer

The use of two radically different mechanisms in one product results in a powerful synergy effect for sound level reduction (sound insulation and sound attenuation).
Important: Mulltilayer material is always applied to vibration-damping material (e.g. STP Black Silver) to achieve the best result.

Area of application:
Wheel arches in the interior, bulkhead, vehicle floor, trunk floor and spare wheel well

Packaging size:

• Mat size: 37.5 X 47 cm
• Thickness 7 mm
• Dimensions sqm/KG: min 4
• Contents per package: 10 mats = 1.76m²

Composition:

1) Top layer soft
2) Heavy mat (MASTIC) 2MM
3) Noise-absorbing layer 5MM consisting of viscoelastic foamed PU< nonbreakingspace/> 
4) Adhesive layer with increased adhesive strength in relation to high temperatures
