Children’s smart phone watches, as children’s wearable products that protect children’s safety and build a bridge of communication between parents and children, have been very popular among children and parents in recent years. Do you know what materials are needed to produce this product? Phone watch waterproof and breathable membrane is one of them.
These breathable, microporous membranes are made from treated expanded polytetrafluoroethylene (ePTFE) and contain a three-dimensional mesh structure.
The membrane pores are designed to prevent the passage of liquids and particles as small as 0.1 microns, while allowing air to pass through easily.
The liquid and particles are then collected onto the outer surface of the membrane.
With its inherent fluid resistance and non-stick properties, our composite materials help remove any dust and liquid trapped on the surface of the membrane.
The waterproof and breathable film for phones and watches is a microporous film made by calendering, extrusion, and biaxial stretching.
The porosity can reach more than 85%, and the air can flow smoothly.
The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
Protect electronic instruments from becoming unusable due to moisture or water.
Compared with other breathable filter materials, it has excellent air permeability. It is difficult to form a thick dust layer on the surface of the film, and the dust can be naturally peeled off.
It is a manufacturer specializing in R&D, production and sales of waterproof and breathable membranes for phones and watches.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
