Sound Controlling & Insulation Products
There are many sources of noise in an automobile, including engine.
Sumitomo Riko's sound controlling & insulation products shut out these noises and keep the inside of the cabin quiet.
Our original urethane is used for the engine cover due to its heat resistant and sound absorption and insulating properties, realizing a high degree of noise reduction even on the engine parts with high temperatures.
In addition, with the increasing demand for materials that can cut down on motor noise while also alleviating the damage caused by heat, Sumitomo Riko has successfully developed a sound reducing material that also conducts heat.
