Problems solved by technology

However, the multilayer ability of polytetrafluoroethylene materials is poor, which cannot meet the requirements of multilayer materials for 5G base station materials. At the same time, polytetrafluoroethylene materials are usually produced in large areas during preparation, and it is difficult to manufacture small-sized materials. Applications There are obstacles in 5G communication terminals
And the glass transition temperature of polytetrafluoroethylene is low, because high-power communication transmission will generate a lot of heat, so the stability of polytetrafluoroethylene also has defects
