Sponge for silent tires
Description
Polyurethane silent cotton, brand new noise reduction technology
The core of silent cotton tires is polyurethane sound insulation foam, which is a polymer compound.
It has the advantages of wear resistance, low temperature resistance and aging resistance. At the same time, the performance of the elastomer is between plastic and rubber. With special silicone bonding technology, it can efficiently absorb sound and reduce the noise of automobile tires.
