GORE mobile phone waterproof technology: expanded polytetrafluoroethylene (ePTFE) material

Outdoors are never meant to be a go-and-go journey, especially in the harsh winter of climatic challenges. A successful outdoor depends on adequate planning and powerful equipment. For wind-resistant and waterproof equipment, the jacket made by GORE-TEX of "Century Fabric" has become the first choice for many outdoor enthusiasts due to its excellent waterproof and breathable performance.

GORE-TEX fabric is American W. L. Gore & Associates, Inc. (Gore Company) Invented and produced a light, thin, strong and durable film that has waterproof, breathable and windproof functions, breaking through the shortcomings of general waterproof fabrics that cannot breathe, so it is known as "the cloth of the century". GORE-TEX fabric is not only widely used in aerospace, military and medical fields, but also adopted by world-renowned brands to make a variety of casual clothing series, so it is listed by the US "Fortune" magazine as the best 100 One of the most popular American products.

But GORE's waterproof technology never stopped there. In addition to outdoor equipment, Gore has accumulated advanced experience and advanced experience covering multiple industries, and has applied expanded polytetrafluoroethylene (also known as ePTFE) as its core waterproofing solution to daily life and society. All aspects of development. With the increasing role of electronic devices in modern lifestyles. With Gore's industry-leading expertise, ensuring excellent waterproof and dustproof performance without compromising acoustic performance has also become one of the important technologies for waterproof mobile phone manufacturing. We have nearly billions of waterproof and breathable products already installed in mobile phone applications worldwide.

The technical hero behind the waterproof phone

Gore uses expanded polytetrafluoroethylene (ePTFE) materials to make adhesive waterproof and breathable products. Expanded polytetrafluoroethylene, or ePTFE for short, is the core material for many Gore solutions. Gore has been developing a variety of life-improving products since 1958, and polytetrafluoroethylene (PTFE) is at the core of these solutions. This polymer has a variety of extraordinary properties, such as high tensile strength, low dielectric constant, UV resistance, and more. In 1969, Bob Gore discovered expanded polytetrafluoroethylene (also known as ePTFE), opening up new possibilities for the application of PTFE.

In the following decades, Gore has accumulated a wealth of knowledge and experience in processing ePTFE and other fluoropolymers: engineers can change the structure, shape and thickness of materials, and then match auxiliary materials to achieve practical uses and Performance characteristics required by customers. The final product can be tough, permeable, rigid, flexible, thin or extremely thick—and a combination of features to meet end-use requirements.

Waterproof products that stand the test of time


With the rapid evolution of consumer upgrades and technological changes, consumers are increasingly demanding waterproof phones, wearables, and other mobile electronic devices. Gore also listed mobile phone waterproof technology as one of the important directions for business development. With Gore's excellent waterproof and breathable solutions, and rigorous R & D and testing processes, while achieving higher reliability of equipment against dust, liquid, and immersion, while maintaining excellent sound permeability, effectively balancing different challenges Pros and cons.

Gore performs a rigorous continuous water pressure (eWEP) test on the product, which measures both how much pressure the breathable membrane can withstand and how long it lasts. Water acts on one side of the waterproof breathable membrane under increasing pressure until the first drop of water penetrates the other side of the breathable membrane, and simultaneously measures the pressure and duration to confirm that the breathable membrane can withstand the specified "pressure / duration "Without problems. This ensures that when the product is exposed to similar environmental challenges during actual application, it can reliably perform its performance.

GORE-the unknown hero behind waterproof technology

GORE handheld electronic equipment has always been favored by major mobile phone manufacturers for its dustproof, waterproof and breathable products. Its excellent performance is the reason why it is the first choice for major manufacturers to produce waterproof mobile phones.

Better overcome dust and acoustic challenges

GORE acoustic breathable products for submerged applications are made of expanded polytetrafluoroethylene (ePTFE), a material technology that optimizes breathability and equipment reliability. The structure of expanded polytetrafluoroethylene includes nodes, fibers, and micropores. This structure helps air and sound transmission while effectively blocking water, other liquids and dust.

Fast and effective pressure balancing

The ventilation structure of GORE pressure-balanced ventilation products can effectively balance the pressure while providing reliable protection against liquid immersion and dust pollution. A highly breathable expanded polytetrafluoroethylene (ePTFE) breathable membrane quickly balances pressure in the front cavity, reduces distortion of the horn and earpiece, and minimizes pressure on the device seals.

Excellent design and installation flexibility

Gore has a number of designs to choose from, which sets it apart from its competitors. Gore products are precise in size and diverse in color, which can meet the needs of designers in various specifications.

Low development and supply risk

Gore is a complete solution provider, meaning it can provide manufacturers with unique acoustic modeling services, rapid design iterations, and superior technical support. In addition, a reliable supply chain ensures that it can provide large-scale production capacity and reliable process integration without affecting acoustic performance.

Over the past half century, Gore has used ePTFE, a revolutionary discovery, to innovate applications in many industries. Gore, who started with science and technology, is still based on rigorous scientific research. For more than 60 years, it has been working hard in the laboratory with a low profile. It has continuously developed more effective waterproof and breathable solutions for the development of waterproof mobile phones.
