路盤の減衰パッド

South China University of Technology developed a bio-based polyester rubber (BBPR) via glutaric acid/sebacic acid copolymerization, achieving a tensile strength of 10 MPa and compatibility with traditional vulcanization processes.

As new energy vehicles and intelligent cockpit technologies evolve rapidly, ride comfort has become a key battleground for automakers seeking differentiation. Addressing the environmental drawbacks and performance limitations of traditional asphalt-based damping sheets, a new generation of polymer composite damping materials is reshaping automotive NVH (Noise, Vibration, and Harshness) control standards through molecular-level innovation.

In high-frequency impact tools such as electric nail guns, rubber damping blocks serve as key vibration-reducing components. Their performance directly affects equipment lifespan and operator safety. Traditional rubber materials often suffer from poor impact resistance, leading to premature equipment failure or hand injuries for users.
