Electromagnetic interference resistance is a new functional requirement for electronic packaging paper, insulating paper and precision electrical auxiliary paper. In electronic production workshops and electrical working environments, complex electromagnetic fields will interfere with ordinary paper’s surface insulation performance, cause tiny current conduction and static accumulation, and affect the safety of precision electronic components. Ordinary paper has no electromagnetic shielding and anti-interference ability, and is easily affected by external electromagnetic radiation, resulting in unstable surface insulation performance, static discharge risk and dust adsorption. For high-precision circuit board packaging paper, electrical insulating paper and electronic equipment gap filling paper, electromagnetic interference will cause potential safety hazards such as component short circuit and signal deviation. Traditional paper modification only focuses on insulation and static resistance, lacking targeted electromagnetic shielding and anti-interference performance, which cannot meet the high-standard protection requirements of electronic industry scenarios. Shandong Ludao Energy Technology Co., Ltd. develops professional paper anti-electromagnetic interference optimization technology. By adding environmentally friendly electromagnetic wave absorption and shielding components, optimizing paper internal insulation structure, we effectively resist external electromagnetic radiation interference, stabilize paper surface insulation performance, and eliminate static discharge risks caused by electromagnetic induction. The solution is safe, non-radiative and environmentally friendly, does not affect paper flexibility and processing performance, improves the safety protection ability of electronic packaging and electrical insulating paper, and expands the application field of high-end functional paper.
