introduction

The sound of the engine compartment is the main sound source for the interior perception of the car. Engine noise, noise from suction and exhaust, and noise from parts vibration are the main sound problems to be solved. The noise of the engine compartment is reduced by adding sound insulation cover and sound insulation felt. . It is made of materials with high temperature resistance, corrosion resistance and good sound absorption function, such as PU foam, glass fiber, non-woven fabric and other materials.

Process: staple fiber needle-punched non-woven process, chemical bonding process

Features: high temperature resistance, corrosion resistance, sound absorption, sound insulation.
