东利科技——产品应用（汽车隔音棉）

汽车隔音、吸音、内饰材料，具有其他同类产品无法比拟的诸多优点

隔音性能好：通常5cm厚的隔音棉就能满足普通场合的隔音要求。

吸音效率高：经检测；5cm厚产品的检测结果为NRC(综合降躁系数）：0.90，若提高密度和厚度，其性能的提升还有很大空间。

阻燃性强：PP（聚丙烯）具有优良的耐热性，可在110°温度下可长期使用。防火性能（阻燃性）材料完全符合汽车内饰要求，能有效提高人生及财产安全性。经国家消防装备质量检验中心实验检测,达到建筑材料燃烧性能国家标准GB8624B1级

环保性能优越：高科技环保材料，无毒，无味，无任何挥发性气体。经检测，其环保性达到国家标准GB18580-2001E1级，和人体皮肤接触不会出现任何过敏现象。

减震抗压效果好：PP(聚丙烯)材质均匀坚实，富有弹性、韧性、耐磨、耐撕裂、抗冲击能力极强。

防潮防水：耐腐防蛀，不发霉，不会有难闻气味的产生。在潮湿环境下，吸音率不变，吸水量不超过自身重量的1%,且易干。PP(聚丙烯)吸水率:0.01%。

防老化：在120℃的环境下，连续1000个小时，吸音无变化。

可塑性强：结构紧密，形态稳定；可压缩及可变形性适用于不同规格或者紧密空间，质地柔软，重量很轻可任意裁剪，易于安装。可使用喷胶、压敏胶带、超声波焊接、热粘贴或者推针粘贴。

高绝缘性：PP(聚丙烯)具有优良的高频绝缘性能，由于它几乎不吸水，故绝缘性能不受湿度的影响。

Good sound insulation performance: usually 5cm thick sound insulation cotton can meet the sound insulation requirements of ordinary occasions.

High sound absorption efficiency: tested; the test result of 5cm thick products is NRC (Comprehensive Noise Reduction Coefficient): 0.90, if the density and thickness are increased, there is still a lot of room for improvement in performance.

Strong flame retardancy: PP (polypropylene) has excellent heat resistance and can be used for a long time at a temperature of 110°. Fire resistance (flame retardancy) materials fully meet the requirements of automotive interiors, which can effectively improve the safety of life and property. It has been tested by the National Fire Equipment Quality Inspection Center and has reached the national standard GB8624B1 for the combustion performance of building materials.

Superior environmental performance: high-tech environmental protection materials, non-toxic, odorless, without any volatile gas. After testing, its environmental protection has reached the national standard GB18580-2001E1 level, and there will be no allergic phenomenon in contact with human skin.

Good shock absorption and compression effect: PP (polypropylene) material is uniform and solid, with elasticity, toughness, wear resistance, tear resistance and strong impact resistance.

Moisture-proof and waterproof: anti-corrosion and moth-proof, no mildew, no unpleasant odor. In a humid environment, the sound absorption rate remains unchanged, the water absorption does not exceed 1% of its own weight, and it is easy to dry. PP (polypropylene) water absorption: 0.01%.

Anti-aging: Under the environment of 120℃, the sound absorption has no change for 1000 hours.

Strong plasticity: compact structure, stable shape; compressibility and deformability are suitable for different specifications or tight spaces, soft texture, light weight, can be arbitrarily cut, easy to install. Can be applied using spray glue, pressure sensitive tape, ultrasonic welding, thermal bonding or push pin application.

High insulation: PP (polypropylene) has excellent high-frequency insulation properties, and since it hardly absorbs water, the insulation properties are not affected by humidity.
