Independently developed by our company, the EVEC-Engineered Polyurethane Foam is specially designed for vehicle noise reduction. It is composed of a high-polymer porous acoustic foam combined with a nano self-healing viscoelastic adhesive layer, delivering excellent sound absorption and long-lasting adhesion. Suitable for both new tires and retrofit applications, it provides a simple yet effective solution for upgrading tire NVH performance.

Key Highlights:

• High Noise Reduction Efficiency: Reduces mid-to-low frequency tire noise by 5–10 dB, particularly effective for electric vehicle applications.

• Strong Adhesion: Nano self-healing viscoelastic adhesive layer maintains firm bonding even in hot and humid environments.

• Exceptional Durability: Resistant to high temperatures, shear forces, and aging, ensuring performance throughout the tire’s full lifecycle.

• Lightweight Design: Low-density structure reduces overall tire weight without compromising acoustic performance.

• Proven Road Test: Verified through 30,000 km of highway driving, maintaining reliable performance and adhesion.
