Tire sound-absorbing cotton special environmentally friendly adhesive

Tire Acoustic Foam Adhesive｜Imported Raw Materials｜Non-Toxic and Odorless｜SGS Certified Processed with imported environmentally friendly raw materials and non-toxic dimethyl ether Tested by SGS to comply with the European Union's REACH standards and better than the national standard GB18583-2008

 

1.Product Positioning

“Mute Defender - Eco-friendly Core”

High-performance environmentally friendly adhesive specially developed for bonding sound-absorbing cotton (polyurethane foam, porous materials) inside the automobile tires to solve the pain point of tire noise, and at the same time reshape the healthy environment inside the car with the ultimate safety standards.

2.Second, the core technical advantages

1. Environmental protection and safety level breaks through the industry ceiling

Traceability of raw materials:

 The core base material adopts a variety of imported environmentally friendly polymers (Germany/Japanese supply chain)

 Solvent upgraded: high purity dimethyl ether (DME) instead of the traditional toxic solvents

→ Achieve the whole process of production/curing is non-toxic, non-irritating odor, and to prevent the release of benzene, formaldehyde, and other pollutants from the source.

 

 

3. The bonding performance accurately matches the tire conditions

Performance Dimensions Parameter Performance Solving Pain Points

Initial adhesion ＞3.5 N/cm² (within 10 seconds) Highly efficient construction, no slippage of acoustic cotton

Final strength ＞8.0 MPa (tire rubber interface) Resistance to high-speed centrifugal force/bumps shedding

Temperature resistance -40℃~120℃ without cracking Adaptable to extreme cold and hot environments

Aging resistance Strength retention rate in the 1000h wet heat test＞90 Service life synchronized with tire cycle

 

 

3. Construction Friendly 
Viscosity adjustable (2000~5000 mPa-s), suitable for spraying/roller coating process.

Surface drying time ≤ 3 minutes (25℃), improve the production line tempo

Low splash formula, reduce equipment pollution

 

4. Application Scenarios and Suitability

Applicable Materials:

 Tire sound-absorbing cotton (PU foam, PET cotton, recycled cotton)

 Tire inner wall (natural rubber/synthetic rubber surface)

 

Vehicles: New energy vehicles (with stringent NVH requirements)/High-end fuel vehicles/Commercial buses.

 

Process support: Provide automatic gluing equipment parameter suggestions and on-site process debugging guidance.
