The new mobile communications standard 5G is steadily advancing. This development is also increasing the demand for materials that facilitate and ensure high transmission rates of 5G signals. This includes the new Desmopan 7000 thermoplastic polyurethane (TPU) from Costco. It exhibits high transparency to 5G frequencies, which reduces signal loss. As a result, it is ideally suited for 5G applications, such as cell phone cases.
5G technology enables higher network speeds, shorter data runtimes, lower power consumption, and more stable connections than previous 4G standards. In order for users to get the full benefits, devices must be equipped with cases that transmit signals with as little interference as possible. This is especially true for thin cases for smartphones. In this application, the low dielectric constant (Dk) and low dielectric loss (Df) of the new TPU family prove to be very beneficial.
In addition, the Desmopan 7000 Series are known for their inherent shock and vibration absorption properties, which are also characteristic of TPU plastics. They also offer excellent abrasion resistance and flexibility over a wide range of temperatures, as well as good elasticity across the entire hardness range. As a result, cell phones equipped with them are also well protected against mechanical shocks. The good adhesion of TPUs to other plastics such as PC or ABS is a major advantage in product development.
Multilayer film for robust backs
Smartphones for 5G reception require more antenna space than their previous counterparts, and manufacturers also have to replace metal backsheets with other materials in order to ensure uninterrupted data exchange.Makrofol SR multilayer PC film with an acrylic top layer is ideal to fully meet these requirements. They are permeable to 5G radio signals and are mechanically very robust.
They also offer a high degree of design freedom. The films can be used to create cost-effective, attractive back covers with a look comparable to glass. Various techniques can be used for this purpose, such as fine three-dimensional structures, non-conductive vacuum metallization, screen printing, and letterpress molding. In addition to a variety of decorative and textured designs, the film surface has a very pleasant feel.
PC for modern radomes
The development of 5G infrastructure also requires a tight network of new and increasingly complex antennas. To protect the outer shell (radome) from the weather, Costron has developed an impact-modified PC with excellent mechanical properties even at low temperatures, UV resistance, and design flexibility due to its high processability.
With low Dk and Df values, they ensure uniform signal transmission and protect state-of-the-art electronics in active antenna installations, miniature base stations, and routers during outdoor use. Helping to ensure a return on investment in 5G network infrastructure.
