Plastics for uninterrupted 5G reception

June 08 2021

The new mobile communications standard 5G is advancing steadily. This development is also increasing the demand for materials that facilitate and ensure the high transmission rates for 5G signals. This includes the new Desmopan 7000 thermoplastic polyurethane (TPU) from Covestro. It exhibits high transparency for 5G frequencies, thus reducing signal losses. The product is therefore highly suitable for 5G applications, for example in protective covers for cell phones.
In addition, products of the Desmopan 7000 series are also known for their inherent shock- and vibration-absorbing properties, which are typical of TPU plastics. They also feature superior abrasion resistance and flexibility over a wide temperature range, as well as good elasticity across the entire hardness range. Cell phones that are equipped with them are therefore also well protected against mechanical impact. In product developments, the fact that the TPU adheres well to other plastics such as polycarbonate or acrylonitrile butadiene styrene (ABS) is a major advantage.
Makrofol SR multilayer polycarbonate films with an acrylic top layer are the ideal choice for requirements such as these. They are permeable to 5G radio signals and mechanically extremely robust.
