We all know that in order not to damage various electronic smart devices in harsh environments, people have put forward higher requirements for the waterproof performance of electronic products. Let’s take a look at the waterproof and breathable membrane material for phones and watches. .
Nowadays, waterproof and breathable valves have many excellent products in the industrial field, which can provide good help to some equipment in the industrial field and extend the service life of the equipment.
Waterproof and breathable valves are indispensable equipment in the industrial field. This equipment has a wide range of uses.
In addition, the waterproof and breathable valve has many functions, so you must understand it in time when using it.
So, what are the general functions of waterproof and breathable valves? The waterproof and breathable membrane for phones and watches refers to a microporous film made of polytetrafluoroethylene as raw material, using special processing techniques, and undergoing calendering, extrusion, and biaxial stretching.
This kind of membrane has excellent breathability, corrosion resistance, aging resistance, high temperature resistance and other properties.
According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, and the porosity can reach 50%–80%.
The waterproof and breathable membrane for phones and watches produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency for some extremely fine particles with a diameter of 0.1um-0.3um. , the filtration level can reach H13-U16.
In addition, biaxially oriented film can undoubtedly achieve ultra-low emissions in intercepting various types of dust generated during the production process of the company, and it fully complies with current environmental protection standards.
