fonosphera^® XB-20TNT

thermoforming solution

Soundproofing, sound-absorbing sandwich panel with thermal insulation properties, consisting of a layer of reticulated polyethylene with a sphere pattern and a body of material with a low mechanical modulus made from a polymer base with mineral filler, laminated onto a layer of 20 mm thick polyester fibre coated with black non-woven fabric (water and oil repellent).

Main characteristics and use:
• High-level of airborne sound insulation
• High-level of sound absorption
• Excellent vibration damping
• Resistant to dirt, swarf, humidity, oil vapours
• Environmentally friendly, contains no bitumen, halogens, phosphates, lead or PVC
• Available in 1 m x 10 m rolls with trimmed edges, also available with adhesive (sphere pattern side)
• Flexible, easy to apply to rigid materials and non-planar surfaces

Ideal for lamination onto metal and fibreglass structures, plastic laminates and wood, for use in engine compartments, machine tool guards, music rooms and construction in general.
