The thermoplastic block copolymer is specially designed for high signal transmission of 5G products.

As 5G networks step into the fast lane, the number of 5G users continues to rise, and the demand for related accessories and products increases several times over. To satisfy the growing demands of the market, Covestro has developed a brand new thermoplastic block copolymer. This material can be used as a product case material, with low Dk/Df characteristics, and is suitable for high-speed signal transmission applications.

Reduced signal loss and impact on signal transmission speed in 5G applications

Compared with 4G, 5G has higher network speed, lower latency, higher reliability, lower power, and more active connections. Therefore, for 5G product case materials, it is very important to reduce signal loss during transmission and reduce the impact on signal transmission speed.

Looking for materials with high signal penetration and a wide range of application scenarios

Covestro's product development team is committed to developing a material with low Dk/Df characteristics, and one that is suitable for high-speed signal transmission, which should feature good durability and flexibility in a wider temperature range, and excellent elasticity in the entire hardness range, to enable it to meet the different needs of various 5G products.

Desmopan®7000 series

To meet the growing demand for 5G ancillary products and product case materials, Covestro has now launched its brand new Desmopan® 7000 series. This series of products has a lower dielectric constant and dielectric loss, which can effectively reduce the signal loss and the impact on signal propagation speed in 5G applications. In addition, the Desmopan® 7000 series not only maintains the outstanding properties of thermoplastic polyurethane, but also has good adhesion to many engineering plastics such as polycarbonate, ABS, and nylon.

“With the continuous development of 5G technology, the demand for 5G applications will increase more and more. The Desmopan® 7000 series is our product that has been developed specifically for 5G applications. It is an ideal solution for 5G product case materials. It can effectively reduce signal loss during transmission, and challenges the transmission limit for 5G applications in various scenarios."
