On December 4th, Gelonghui reported that Shanghai Pret Composites (002324.SZ) announced that the company and its subsidiaries recently received the "Notice of Grant of Invention Patent Rights" issued by the State Intellectual Property Office. The invention patent is titled "An LCP Liquid Crystal Polyester Fabric for Preparing Low Dielectric, High Peel Strength PCB Copper Clad Laminates and Its Preparation Method."

This invention relates to an LCP liquid crystal polyester fabric and its preparation method for making low dielectric, high peel strength PCB copper clad laminates. This invention achieves the improvement of compatibility between fully aromatic liquid crystal polyester and polyphenylene oxide resin by optimizing the structure and properties of the materials themselves, requiring only a small amount of the functional masterbatch prepared to do so, while maximizing the retention of the original mechanical and heat-resistant properties of the liquid crystal polyester fibers.
