Hankook updates sound absorption technology

Monday 11th September 2017 | 0 Comments

 

Hankook reports that it has updated its sound absorber technology with a new foam and adhesion process that further reduce tyre weight. The next foam is said to reduce internal noise levels by as much as 5 to 7 dB(A).

The acoustic foam is now being adhered with partial coverage of a heat-resistant silicone-based glue instead of being fixed in place with a full-surface coating. This updated adhesion process in conjunction with the lighter-weight acoustic foam allows for further weight optimization, Hankook said.

Hankook’s original sound-absorber technology was introduced in 2016 to help reduce interior noise. It has been used in original equipment tires on the Audi RS5 Coupé, Audi Q7/SQ7 SUV, and the new Opel/Vauxhall Insignia.
