Hankook has now automated application of its sound absorber technology. Previously, the acoustic foam used had been fixed in place using a thin layer of the company’s Sealguard material, applied all over in a labor intensive process.
A new, lighter-weight foam material has also been developed for this purpose. In addition, the Sealguard material has been replaced by a silicone-based glue that only needs to partially cover the inside of the tire, instead of the full-surface application previously used.
This not only significantly reduces weight but enhances the heat-resistance properties of the new technology, resulting in improved load-bearing capacity and durability, particularly under full load conditions and at top speeds.
Further to this, the technology is also now applied in Ventus S1 Evo2 tires for fitment to both the Opel Insignia Grand Sport saloon and the Sports Tourer estate models in size 245/45 R18 96W.
