Supply the ePTFE waterproof breathable dust film

the ePTFE waterproof breathable dust film 

 ePTFE the waterproof breathable dust film has three main functions: 
 Waterproof :0.1-1 .0 micron pore, pore size of less than drops 10,000 times, so that water can not be passed, the effective protection of the sensitive class member, to avoid liquid erosion, and improve the product life. 
 Breathable: the pore size is greater than the water vapor 700 times, while waterproof, allowing the smooth passage of air, can be cooled efficiently, and to prevent the product wall fogging, air pressure balance the interior and exterior spaces. 
 Dust resistance: the microporous channel in the membrane to form a mesh-dimensional structure, uniform dense pore distribution, the dust encountered barrier, achieve effective dust effects, the minimum can capture 0.1 micron particles. Protection class: IP67.
