ICET ® Polyester Fiber Sound-absorbing Material
1. Product Overview:
Polyester fiber sound-absorbing material is specially designed for buses. No glue or other media is included in the molding process, making it highly environmentally friendly. It not only has excellent sound-absorbing effect, but also meets the standards of the bus industry
After hot pressing, it is made into a cocoon like cotton shape. By utilizing heat treatment methods to achieve density diversity, it becomes an excellent sound-absorbing material with no volatility.
Application: Composite materials for bus body side panels/headliner/engine compartment
