Polyurethane Tire Sound Absorbing Sponge

Polyurethane tire sound absorbing sponge is a special foam made of polyurethane material, which is mainly used to reduce the noise generated by the tire during driving. The design goal of this sponge is to improve the quietness of the vehicle, especially when driving at high speed or on complex roads, it can effectively reduce tire noise.

1. Excellent sound absorption performance:
Polyurethane sponge has excellent sound wave absorption ability and can effectively reduce the noise generated by the contact between the tire and the ground.

2. Good elasticity and wear resistance:
This foam material can not only effectively absorb sound, but also withstand long-term friction and compression, is not easy to deform, and increases the service life.

3. Light weight and small size:
Polyurethane sponge is light and does not take up too much space, so it will not significantly increase the weight of the tire or affect the performance of the vehicle.

4. Environmentally friendly:
Polyurethane materials can usually be recycled and reused in an environmentally friendly manner through appropriate recycling, which meets the environmental protection needs of the modern automotive industry.

5. Good anti-aging and anti-ultraviolet performance:
Polyurethane has strong aging resistance and can still maintain good performance after long-term use.

1. Automotive industry:
Polyurethane sound-absorbing sponge is widely used in car tires to help reduce tire noise generated by wheels, improve the quietness of the car, and improve driving comfort.
It can also be used for tire noise control of high-end electric vehicles, luxury cars and racing cars, especially in long-distance driving or complex road conditions.

2. Public transportation:
Such as subways, buses and other transportation tools, reduce tire noise during driving and provide a quieter riding environment.

3. High-end machinery and equipment:
Such materials may also be used in high-noise industrial machinery and equipment to reduce vibration and noise and improve the comfort of the working environment.

4. Other transportation tools:
Including airplanes, railway vehicles, etc., reduce the noise generated by tires or contact surface friction and improve the riding experience.

Polyurethane is known as the "fifth plastic" and is widely used in many fields due to its excellent performance and material stability, including insulation, sound insulation, shock absorption, and thermal insulation.

Polyurethane Tire Sound Absorbing Sponge

When polyurethane sound-absorbing sponge is added to the inside of the tire, it can effectively block the propagation of sound waves.

More importantly, it allows engineers to have greater space for tire surface formulations and patterns, and can comprehensively consider the wear resistance that has always been opposed to silent tires, thereby achieving a comprehensive performance improvement in noise reduction, shock absorption, and wetland drainage.

So also can be used as filling material for aircraft seats, shock-absorbing materials inside cars, and so on.
