Comfort Mat Dark Premium D2 2.3 mm. This is a high quality product. It is used in places that worry about the strongest noise. Such as Floor, boot, wheel arches, boot sides and plastic wheel boxes from the outside. Aluminum butyl mat dampens vibrations (anti-droning mat). It consists of a special butyl mixture of the D-formula, thanks to which its mass is 40% lower than other manufacturers with better damping efficiency. It is practically used throughout the car: doors, body and chassis, dashboard, boot, wheel arches and trunk. The product consists of: 1. A special butyl adhesive mixture in which a modified elastomer (elastomers are shape-resistant, but elastically deformable plastics) is used. 2. Aluminium foil Advantages of products: - High vibration damping factor (MLF 0.35). Other standard products with similar thickness and greater weight have MLF 0.2 - 40% less weight than the mats of other manufacturers with the same thickness - Has sealing and corrosion protection properties - material resistant to moisture and high temperatures. - 2.3 mm thick - sheet size 500x700mm - sheet weight 0.75 kg (2.15 kg/m2) Application of the COMFORT MAT mats: basically you need to know that there are two types of insulation mats (1: anti-droh-mat 2: soundproof) and each mat is seen as a single step of work. The anti-droning mat is used to stabilize the vibration of the vehicle body that is prone to movement (while driving). The stabilisation of the resonance body reduces a large part of the causes noise in the vehicle interior. To achieve the maximum damping effect, the second step would now follow. The complete surfaces that have been glued with the anti-drohn mat are now glued to the soundproofing mat. Thus, the thermal and acoustic effect of the insulation would be at the
