The acoustic foam must be heat-fusion bonded onto the barrier. No adhesive shall be used between the foam and the barrier.
The acoustic foam must be combustion modified polyether PU foam. The barrier material is a PVC-based polymer alloy loaded with inert mineral fillers. The barrier must have a 140 gsm black non-woven backing. The backing material must also be heat-fusion bonded onto the barrier. No adhesive shall be used.
The composite material must be capable to stand 120°C continuous service temperature and short term intermittent temperature of 140°C.
