Covestro introduces plastic that does not interfere with 5G signal reception

The new mobile communication standard 5G is steadily advancing
.
This development has also increased the demand for materials that facilitate and ensure high transmission rates of 5G signals
.
This includes the new Desmopan® 7000 thermoplastic polyurethane (TPU) from Covestro
.
Its high transparency to 5G frequencies reduces signal loss
.
Therefore, this product is very suitable for 5G applications, such as mobile 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 the user to obtain the full benefit, the device must be equipped with an enclosure that transmits the signal with as little interference as possible
.
This is especially true for thin phone cases for smartphones
.
In this application, the low dielectric constant (Dk) and low dielectric loss (Df) of the new TPU series proved to be very beneficial
.

In addition, the Desmopan® 7000 series is also known for its inherent shock and vibration absorption properties, which are also characteristic of TPU plastics
.
They also have excellent wear resistance and flexibility over a wide temperature range, as well as good elasticity across the entire hardness range
.
Therefore, phones equipped with them are also well protected from mechanical shocks
.
In product development, the good adhesion of TPU to other plastics such as PC or ABS is a major advantage
.

Multilayer Films for Rugged Backs

Smartphones for 5G reception require more antenna space than their previous counterparts, and manufacturers must also replace metal backplanes with other materials to ensure uninterrupted data exchange
.
Makrofol® SR multilayer PC film with an acrylic top layer is the ideal choice 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 film can be used to create cost-effective, attractive back covers that rival glass in appearance
.
Various techniques can be employed for this, such as fine three-dimensional structures, non-conductive vacuum metallization, screen printing, letterpress forming, and the like
.
In addition to a variety of decorative and textured designs, the film surface has a very comfortable feel
.

PCs for modern radomes

The development of 5G infrastructure also requires a tight network of new and increasingly complex antennas
.
To protect the outer cover (radome) from the weather, Covestro has developed an impact-modified PC with excellent mechanical properties even at low temperatures, UV resistance and design flexibility due to its high processability sex
.

Their low Dk and Df values ​​ensure uniform signal transmission and protect state-of-the-art electronics in active antenna units, micro base stations and routers during outdoor use
.
Help ensure return on investment in 5G network infrastructure
