What are the materials of the waterproof breathable valve?

Waterproof and breathable valve is one of the essential components in some products. It not only has waterproof effect, but also can achieve breathable effect. It can even minimize the harm of blisters to the product, and at the same time, it has a great effect on the improvement of product quality. significance. High-quality waterproof and breathable valve materials can bring good use effects and high quality assurance, and there are many kinds of materials to choose from.

The first is the plastic material. Plastic materials can be divided into spandex and polyester. Spandex has the characteristics of abrasion resistance, softness, and strong toughness. It is not easy to age and has high acid and alkali resistance, but it is not easy to shape. It is often used in the maintenance of some waterproof and breathable valves. It is favored by many consumers because of its easy cleaning and environmental protection. Compared with spandex materials, polyester materials have better formability and standard stability, and their flame retardancy and high temperature resistance are also very good.

Followed by metal materials. Metal materials can be divided into materials such as stainless steel, aluminum alloy, copper and titanium. Stainless steel has the characteristics of corrosion resistance, high toughness and high temperature resistance, and is widely used in waterproof and breathable valve parts of some electronic products. Aluminum alloy materials have the characteristics of strength, toughness, lightness and corrosion resistance, and are often used in vehicle water tank sealing parts in automobile manufacturing. Copper materials are more expensive and are mainly used in domestically produced high-end water treatment equipment. Titanium materials also have good toughness and corrosion resistance, and are used in some high-demand products with relatively high cost performance.
The third is the rubber material, which has good sealing and plasticity, and also plays an important role in the manufacture of waterproof and breathable valve products. Rubber materials are mainly divided into three categories: styrene-butadiene rubber, neoprene rubber and fluororubber. Among them, styrene-butadiene rubber has relatively good oil resistance and solvent resistance, while neoprene rubber has outstanding performance in high temperature resistance, so it is often used in the production of waterproof and breathable valves for automobiles and electrical appliances. Fluororubber is more resistant to acid and alkali, and has better tolerance to hardeners and high-temperature environments. It is widely used in some military and aviation equipment.

The last thing that should be mentioned is nanomaterials. In fact, the nanomaterials in the waterproof and breathable valve are processed on the basis of other materials through special technology, which has the magical effect of adjusting product performance and optimizing functions. Taking nano-silicon as an example, it has super anti-foam and anti-crack properties, which can improve the waterproof effect of the waterproof and breathable valve to a higher level, so that the waterproof and breathable valve products with smaller size can also give full play to their waterproof and breathable performance. effect.
