LEVERKUSEN, Germany—Covestro has introduced a thermoplastic polyurethane designed to protect your phone—and your phone's 5G signal.
Covestro's new Desmopan 7000 TPU is highly transparent to 5G signals, thus reducing signal losses, and works well in protective covers for cell phones.
Because 5G technology enables higher network speeds, shorter data run times, lower power consumption and more stable connections, devices must be equipped with cases that transmit signals with as little interference as possible. This is especially true for the thin protective covers of smartphones.
Desmopan 7000 has low dielectric constant and low dielectric loss at these wavelengths, Covestro said, and the TPUs are known for their shock- and vibration-absorbing properties.
They also feature superior abrasion resistance and flexibility over a wide temperature range, as well as good elasticity across the entire hardness range.
TPUs also adhere well to other thermoplastics such as ABS or polycarbonate that give the designers of phone protectors a great deal of design freedom, the company said.
