�� One sentence to get to know FEP
FEP (fluorinated ethylene propylene copolymer, also known as F46)——The co crystallization of tetrafluoroethylene and hexafluoropropylene has a melting point of 250-270 ℃ and a continuous use temperature of -85 ℃~200 ℃, with a dielectric constant of only about 2.1. It is the "evolutionary form" of polytetrafluoroethylene (PTFE): it inherits the chemical inertness and electrical insulation genes of the "plastic king" and also has the processing advantages of thermoplastic plastics - extrusion, injection molding, and encapsulation, which PTFE cannot achieve.
⚡ Why is FEP currently the most worthwhile high-frequency insulation material for layout?

�� Market data
The FEP silver plated insulated cable market is expected to reach 5.541 billion yuan in 2027, with a compound annual growth rate of approximately 18.37% from 2023 to 2027. The window for domestic substitution has opened, and policy dividends continue to be released - Jiangsu Province provides up to 20 million yuan in head set insurance compensation to FEP used for the validation of cleaning tank liners in processes below 14nm, and Zhejiang Province includes FEP based high-frequency copper-clad laminates in the 2025 Pioneer Leading Goose R&D Plan.
