Exhaust Systems

Glass fibre for sound absorption of exhaust systems

The mineral composition of 3B glass fibres makes them extremely durable and resistant to high temperatures and exhaust fumes’ chemical.

These inherent properties of 3B glass fibres have triggered, some 25 years ago, the use of glass filled silencer systems that still equip today most vehicles globally.

The main advantage of 3B glass fibre is that it can easily be transformed into a well-texturized material that leads to an optimized acoustic absorption across the entire frequency spectrum. Also being able to sustain temperature peaks up to 800°C, 3B glass fibres are the materials of choice in the most demanding sound absorption exhaust systems without showing any fibre deterioration across the whole vehicle’s lifetime.
