The BISCO® A2 Sound Barrier meets aircraft standards for flammability, smoke density and toxicity, and is approved to the Airbus ABS5708 material specification. This material is used to block the transmission of sound and demonstrates excellent performance in low frequency noise reduction.
An engineered solid silicone rubber, it provides excellent transmission loss performance in extreme environments while maintaining physical properties. It is temperature stable from -50 C to +180 C, with flame resistance and low moisture absorption.
Fillers allow the A2 material to pass the aircraft radiant panel flame test FAR25.856 (a) from aerial densities of 1.2 kg/m² to 8.2 kg/m² (0.25 lbs/ft² to 1.68 lbs/ft²). Also appropriate for use in railcars. It is available in a light gray color in a standard width of 1000 mm in roll lengths of 5 m and 10 m.
