AUTOMOBILE MANUFACTURING INDUSTRY SOLUTION

The automobile application is more popular in our modern life,cars driving on the way will meet different weather and road conditions.Lighting enclosures are exposed to the external environment,dust fog,rain-snow,road debris and muddiness etc will affect lamp lighting.The change of external temperature can also lead to light-body inside and outside with differential pressure change, thereby affect the light body itself sealing performance.It is very easy for the device to absorb contaminants and increase fogging when the temperature difference is bigger between inside and outside on the light body.Eventually cause light fault,thus affecting vehicle safety.

Unique waterproof breathability function of Puw breather valves can provide lasting protection for the car lamp from external moisture,dust,oil stain and other dirt;while exchanging the gas between inside and outside as the pressure changed,so as to balance the differential pressure,drop the temperature difference,reduce pressure and foging on the light sealing enclosure,prolong the service life of product.

一、Product performance

1、Safety degree of waterproof,dustproof and breathability:IP65K―IP68K

2、Features of PUW microcellular structure ePTFE as below:

（1）Water-repellent,anti-oil   
    
（2）Prompt moisture and steam send out

（3）Strong chemical inertness   
  
（4）Anti-UV 

（5）Endure extreme temperature

二、Main advantages

1、High efficient breathability: a、Largely reduce the foging on the
car lamps. b、Fast balance the differiential pressure between inside
and outside,thereby lowering enclosure design and manufacturing costs.

2、High efficient waterproof grade:Can be waterproof,prevent dirt and contaminates into the light body interior,so as to protect the internal electronic components,reduce the failure rate.

3、Easy installation:can reduce the complexity of the light body structure; simplified assembly process.
