Thermoplastic polyurethane is specially designed for the high-speed signal transmission of 5G devices and accessories.
Reduced signal loss and signal distortion in 5G applications
Compared with 4G, 5G comes with higher network speeds and reliability, lower power and latency, and is capable of sustaining more active connections. Therefore, for 5G device casing materials, it is vital to reduce signal loss during transmission and reduce signal distortion.
TPU materials with high signal penetration and excellent shock-absorption features
Covestro has developed the Desmopan® 7000 series with low Dk/Df characteristics suitable for high-speed signal transmission applications. It maintains the excellent shock-absorbing and vibration-damping features of thermoplastic polyurethane, which are needed to provide the best possible protection for mobile devices.
Our solution – the Desmopan®7000 series
The Desmopan® 7000 series also features good durability and flexibility at a wider temperature range and excellent elasticity throughout the entire hardness rangeto meet the different needs of various 5G products. The material also demonstrates good adhesion to several engineering plastics such as polycarbonate, and ABS.
“With the continuous development of 5G technology, the requirements for 5G applications will only increase. We have developed Desmopan® 7000 specifically for 5G applications. It is an ideal solution for protective 5G device covers as it can effectively reduce signal loss during transmission and challenge the transmission limitations of 5G applications."
