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.

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.
