Copper Metallized PPS Film is an electrically insulating film using PPS film, which is commonly used in the capacitor field due to its performance characteristics. PPS plastic (polyphenylene sulfide) is a high-performance thermoplastic engineering plastic known for its superior properties, including high temperature resistance, corrosion resistance, and excellent mechanical properties.



Unlike metals, shielding laminates are non-conductive at their core. While metals such as copper are inherently conductive, shielding laminates formed from non-metals are ideally suited for use as insulation or signal shielding materials that do not respond to electric fields and resist the flow of charge.

IP stands for Ion Plating, a more detailed categorization of PVD technology. PVD methods include vacuum deposition, sputtering and ion plating (IP). IP is considered the best technology for adhesion and durability.

In a vacuum, the coating material is evaporated or sputtered and deposited onto the substrate to form a thin film. Since there are no air molecules to interfere, the coating material can travel in straight lines and form highly uniform layers.

EMI solutions consist of three main routes: EMI shielding, printed circuit board grounding and EMI absorption.

  • Electromagnetic Interference Shielding involves blocking electromagnetic noise and attenuating cable-collected noise. It uses high-reflectance materials (usually low-resistance metals) to encase or seal openings in target devices for EMI and EMS solutions.
  • Printed Circuit Board (PCB) Grounding refers to grounding electronic equipment electrically to prevent electric shock, treating the Earth as a massive conductor at zero electric potential. Two grounding methods are employed: frame grounding and signal grounding on PCBs.
  • Electromagnetic Interference Absorption (EMI Absorption) utilizes magnetic loss, dielectric loss, and conduction loss to convert radio wave energy into thermal energy. EMI absorbers have a wide range of applications.
