With the continuous development of smartphones, consumers' requirements for cell phones are getting higher and higher. In addition to functionality and performance, the texture, feel and durability of the phone have also become an important consideration. In these aspects, PU foam (polyurethane foam) as a new material, is gradually becoming the choice of innovation in the cell phone industry.
In the choice of cell phone internal padding materials, most of the plastic or metal and other hard materials, not only increase the weight of the phone but also affect the comfort and feel of the phone. But with the introduction of PU foam, this situation has been improved. PU foam has the advantages of being light, soft, flexible, sound-absorbing, and sound-insulating, and can be well adapted to the internally shaped structure of the phone to provide more stable support and make the phone more lightweight, and easy to grip.
PU foam also has better durability and pressure resistance, which can effectively reduce the damage to the phone in case of drops or other accidents, and protect the internal parts of the phone from damage. At the same time, PU foam can also effectively isolate the phone's internal electromagnetic waves and noise, and improve the phone's signal quality and clarity of calls, making the phone more stable and smooth in use. In addition to the above advantages, PU foam also has environmental protection, safety, and other characteristics. Compared to traditional filling materials, PU foam does not produce a lot of waste and harmful gases like plastic, for the environment will also be better. At the same time, the production process of PU foam does not contain any harmful chemicals to the human body, and the use of more safe and reliable.
PU foam as a new type of filling material has been widely used in the cell phone industry, and has achieved very good results. With the continuous progress of technology and consumer demand for cell phone quality and other aspects of the improvement, PU foam will continue to play an important role in the future, and become the choice of cell phone material innovation.
Through die-cutting process, PU foam can be cut into various shapes and sizes, and the die-cut foam products can be more easily bonded and fixed to suit the needs of different fields and improve their use and convenience.
