Waterproof Materials for Technology and Electronic Applications

As commercial use of electronics increases, manufacturers have developed many materials which can be waterproof and water-resistant. This can include waterproof plastics such as polycarbonate, TPE, and TPU. These are just a few of the most common types of waterproof materials used in technological and electronic applications.


Polycarbonate is a thermoplastic polymer known for being tough and resistant to many forms of stress. It resists stress from extreme temperatures, impact, and electric surges. Polycarbonate also can be useful in optical applications. Uses for polycarbonate include electrical machinery, telecommunications equipment, security components, and even DVD and CD discs.


Thermoplastic elastomer, or TPE, is a mix of polypropylene and rubber. The addition of rubber can allow TPE to be resistant to heat while retaining much the durability of a plastic. TPE also has a moderate amount of stretch but can retain much of its original shape when released. Long-term stress is less likely to induce creep, which is permanent disfiguration on the material. TPE can be used for items like waterproof cases, machine casings, remote controllers, and medical devices.


TPU, or thermoplastic polyurethane, is another type of elastomer which can be used in technology and digital applications. Like TPE, TPU can be heat resistant and elastic. TPU has the added advantage of having some level of ability to be remolded and reused. Uses for TPU include instrument panels, medical devices, and waterproof plastics for mobile phone cases and electronic device cases.


The use of silicone has been growing in digital and technology applications. Silicone is a synthetic compound which has heat and water-resistant properties and it has several forms which can be used in many applications. Some forms include rubber, resin, grease, oil, and caulk. Applications for silicone are many, including component casings, seals, moldmaking, appliances, touch keyboards, and electronic cases.


Aluminum is a soft metal which is abundant on Earth. It is also generally considered safe for human use as well as for animals and most plants. Unlike many other common metals, aluminum does not corrode or rust easily, which makes it a good metal to use in applications requiring the strength of a metal structure without being affected by corrosion. Aluminum can also be recycled, which is appealing to reduce waste and market to environmental concerns. Aluminum is often used in machinery and electronic casings, electronic frames, and appliances.

Waterproof plastics, such as Elite plastics, can have a broad range of industrial, medical, and commercial applications. As more and more consumers are driven to purchase waterproof devices, the need for waterproof materials is likely to increase.
