Waterproof breathable membrane with IP68 adhesive backing, wearable device sensor, car light

Guangdong Migao Technology Co., Ltd. focuses on the research and development, production, and sales of waterproof and breathable membrane products. The products include ePTFE waterproof breathable membrane die-cutting parts, waterproof breathable horn mesh, etc.
EPTFE is a new type of waterproof and breathable material, and its chemical name is expanded polytetrafluoroethylene (ePTFE fine powder resin). Polytetrafluoroethylene is expanded and stretched to obtain a uniform, three-dimensional network structure with the same pores. This network structure forms micro pores of 0.1-1.0 microns, with pore sizes smaller than water droplets by 10000 times and larger than water vapor molecules by 700 times. It can reliably block liquids such as water and oil for a long time and allow air to easily pass through. At the same time, the mesh like three-dimensional structure formed by the microporous channels inside the membrane effectively blocks dust and achieves dust-proof effect, capturing particles as small as 0.1 microns.
Waterproof breathable membrane has three main functions:
Waterproof: Micro pores with a diameter of 0.1-1.0 microns, with a pore size less than 10000 times that of water droplets, prevent moisture from passing through, effectively protect sensitive components, prevent liquid erosion, and improve product service life.
Breathable: The micropore size is 700 times larger than that of water vapor, making it waterproof while allowing air to pass through smoothly, effectively dissipating heat, preventing fogging on the inner wall of the product, and balancing the air pressure inside and outside the space.
Dust prevention: Micro porous channels form a mesh like three-dimensional structure within the membrane, with uniformly dense micro pores distributed to block dust and achieve effective dust prevention. Small particles can capture particles as small as 0.1 microns.
Main functions:
1: Effectively blocking moisture, salt, and other corrosive liquids, ensuring that sensitive components of the equipment are safely exposed outdoors.
2: Contact with liquids such as water and oil can quickly restore breathability.
3: The dense and uniform distribution of micropores not only provides waterproofing and breathability, but also effectively blocks dust,
4: Balance pressure, prevent air and moisture around the sealing components from entering the body, and protect the integrity of the seal.
5: Protect components from weather conditions and withstand immersion in water and other liquids.
6: Make the protected components easy to clean and not affected by corrosive pollutants, ensuring component performance and service life.
7: Prevent direct sunlight, have strong chemical inertness, and withstand high temperatures.
8: Thin and lightweight, with good concealment, it brings convenience to design and production, and is an ideal waterproof and breathable product.

Waterproof breathable film (breathing paper) is a new type of polymer waterproof material. In terms of production process, the technical requirements for waterproof breathable membranes are much higher than those for general waterproof materials; From a quality perspective, waterproof breathable membranes also have functional characteristics that other waterproof materials do not possess.
In the state of water vapor, water particles are very small, and according to the principle of capillary motion, they can smoothly penetrate to the other side of the capillary tube, resulting in air permeability. When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (water molecules "pull and resist" each other), water molecules cannot smoothly detach from the water droplets and penetrate to the other side, which prevents water infiltration and gives the vapor permeable membrane waterproof function.
Working principle of waterproof breathable membrane
Waterproof breathable membrane materials have gone through waterproof glue, PU film, TPU film, E-PTFE (polytetrafluoroethylene). Today, we will focus on learning about PTFE materials for waterproof breathable membranes.
EPTFE is a new and efficient high-tech waterproof and breathable product, and its chemical name is expanded polytetrafluoroethylene (EPTFE fine powder resin). It is a three-dimensional mesh structure film that is rapidly stretched by expanding polytetrafluoroethylene to achieve uniform and identical voids.
This network structure forms a small pore size of 0.02 microns, with 3 billion micropores per square centimeter of area. For this reason, it can block the passage of liquid water cargo and solid particles, while allowing air to freely pass through, thus achieving waterproof, dustproof, and breathable functions.
EPTFE has the same excellent chemical and physical properties as polytetrafluoroethylene. What is it for
Almost all chemicals and volumes exhibit inertness, can withstand strong acid and alkali corrosion, resist high and low temperatures, and have hydrophobicity and oleophobicity. Therefore, they are very suitable as filter media in harsh working environments with high requirements for waterproofing and dust prevention.
Waterproof breathable membrane
Ptfe waterproof breathable membrane
The waterproof breathable membrane series products are made of a flexible and elastic microporous material - polytetrafluoroethylene (e-ptfe). Polytetrafluoroethylene microporous material has high porosity, uniform pore size distribution, breathability, low friction coefficient, and extremely low adsorption. It is not only dust-proof, oil repellent, hydrophobic, and thermally stable, but also resistant to chemical media corrosion, UV resistance, etc. It can continuously exert its breathable function at temperatures ranging from -40 ° C to+150 ° C.

Waterproof breathable film is mainly reflected in waterproof breathability, dustproof breathability, and bacterial prevention breathability. It is widely used in fields such as automotive, medical, environmental monitoring, packaging, and electronic sensor component protection. It is called "breathable material".
