    ——Sound-absorbing cotton As the living standard improves day by day, people's demand for car functions is gradually increasing.
    On the basis of safety and speed, a more comfortable space environment is required
    .
    When a car is driving, the noise generated by the operation of the engine and other equipment and the noise generated by the external environment will seriously affect people's driving experience
    .
    Therefore, the sound insulation and noise reduction performance of automobiles has increasingly become one of the important standards of automobile comfort
    .
    Since sound-absorbing cotton is a porous material, it can convert sound energy into heat energy through friction between sound waves and the material, thereby achieving a good sound-absorbing effect.
    It is currently one of the sound-absorbing and noise-reducing materials commonly used by automobile OEMs
    .
    Sound-absorbing cotton can be applied to many parts of the car, such as door trim panels, hoods, dashboards, roofs, trim panels, trunks, etc.
    , which can effectively reduce noise from all directions into the cockpit
    .
    Due to the differences in the design concepts of different models, the area where sound-absorbing cotton is used is also different

    In the automotive lighting industry, automotive micro-permeable products (ventilating plugs, venting membranes) can help automotive lights quickly adapt to temperature and pressure differences.
    However, when the air humidity in the automotive lights is high and the humidity cannot fully flow and diffuse into the environment, The cold zone with low dew point of car lights is prone to water mist
    .
    At present, the solutions to the problem of car lamp fogging in the industry mainly include two kinds: anti-fog coating and desiccant
    .
    The anti-fog coating mainly adopts anti-fog nano-coatings.
    Due to the super-hydrophilic nature of the coating, water molecules cannot form water droplets on the surface, so as to achieve the anti-fog effect
    .
    The car lamp desiccant solves the problem of fogging by adsorbing the water vapor in the car lamp, and improves the durability of the car lamp and the lighting quality
    .
    According to industry experience, about 40-50% of cars use desiccant to solve the problem of fogging of car lights each year.
    Among them, each car headlight usually uses 1 pack of 10g desiccant, 1 pack of 5g desiccant, and each taillight usually uses 1 pack of 10g desiccant and 1 pack of 5g desiccant.
    1 package of 5g desiccant, calculated at 4 yuan per package for 10g desiccant and 2 yuan per package for 5g desiccant, the market scale of the automotive desiccant industry in 2019 is about 164,164,400 to 20,576,800 yuan
    .
    In the future, the ePTFE membrane industry will show the following development trends: Multi-materials meet the realization of more complex functions
    .
    The "C-F bond" in the chemical bond of PTFE has high energy, stable performance, and strong inertness, which makes it extremely resistant to chemical corrosion.
    The porous nature of ePTFE makes it an excellent composite substrate
    .
    After ePTFE and non-woven fabrics, SiO2 aerogel, PP, PU, ​​PI, PPS, Nafion-H and other materials are compounded, new materials with a variety of new or improved characteristics can be formed, which provides various problems for academic and industrial circles.
    Solutions at the material end
    .
    Continue to produce new application areas
    .
    It has been 50 years since ePTFE first came out in 1969, during which a large number of application fields and application scenarios have been produced.
    The application of ePTFE has penetrated into all aspects of human life, and is still opening up new subdivided application fields with technological progress.

    .
    The progress of localization has accelerated
    .
    At present, my country's high-end ePTFE materials mainly rely on imports, and most of the market is monopolized by foreign giants such as Gore, Nitto Denko, Donaldson, etc.

    .
    For example, in key projects such as the C919 civil aviation aircraft and Dongfang Electric's hydrogen fuel cell, key materials related to PTFE are still provided by foreign suppliers
    .
    If the procurement of these materials is restricted, it may have an adverse impact on downstream industries, especially key areas such as military industry, medical care, and aerospace
    .
    In April 2017, the "Thirteenth Five-Year Plan for Scientific and Technological Innovation in the Material Field" issued by the Ministry of Science and Technology listed high-performance membrane materials as an important direction for national development in the material field
    .
    Thanks to the state's policy and financial support in related fields, the progress of localization of new materials has been accelerated
