（1）吸音能力提升明显：提高NVH效果，在一定的频率下，达到99%的吸音效果；
（2）耐高温、阻燃性及各种发动机舱液体：避免老化、被腐蚀及导致吸音性削减。耐发动机高温，且能有效阻燃，且自熄焰火。该吸音棉能耐水、防冻液、电池液、制动油、机油等液体，常温下吸音棉吸收液体所需时间至少1h以上，具有超强的耐液性。且在潮湿环境下，能保持高效的吸音效果。在180℃的高温下12h后，吸音性能不变，外观无变化；
（3）具备定型及保持自身形状的能力：在狭窄环境内避免与周边件干涉。
当吸音棉厚度较低时，通过热压成型即可保持产品定型；为满足厚度达到20 mm时产品仍具有优秀的定型能力，在无纺布面增加热熔胶，增加热压时间，提高热压温度使热熔胶与玻纤、无纺布之间融合更紧实，使产品具有超高的粘结强度和弯曲强度。
最后应说明的是：以上所述仅为本发明的优选实例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
