Low dielectric constant LCP film for 5G applications

We, Sumitomo Chemical, are developing a liquid crystalline polyester (LCP) with a low dielectric loss tangent for the 5th generation mobile communication system (5G).

The soluble LCP, which is our proprietary technology, can be cast into thin films and impregnated into sheet substrates, and its use is expanding to copper-clad laminates and speaker diaphragms, etc. In addition, we are working on developing LCP for a new low dielectric constant film for post-5G technologies.

We will also continue to work on material development to achieve 5G and CASE (Connected, Autonomous, Shared & Services, Electric), which is said to be the way of the next generation of automobiles. Sumitomo Chemical strives to be an entity that will help create a rich lifestyle for everyone.
