From "invisible supporting role" to "core hub": automobile sealing strips usher in both volume and price rise and material revolution

Under the background of increasingly stringent NVH (Noise, Vibration and Acoustic Vibration Roughness) performance and protection requirements for the three electric system of the whole vehicle, the automobile sealing strip once regarded as "invisible supporting role" is ushering in an unprecedented market opportunity. Industry consensus points out that due to the elimination of engines in pure electric vehicles, environmental noise such as wind noise and tire noise have become the main pain points. In order to achieve the ultimate noise reduction effect, the average length of the sealing strip used in new energy vehicles has increased by 10% -20%, and the number of sealing lanes has generally increased from 2 to 3 to 4, directly driving the value of the vehicle to increase by more than 20%. In addition, the waterproof and dustproof requirements of battery packs, motors, and high-voltage wiring harnesses have also opened up a huge pure incremental market for sealing systems.
