  • Low outgassing and strong adhesion on foil and separator surfaces

    Insulation and Barrier Tapes

    • PET, PI (polyimide), and PP base films with high dielectric strength
    • Used between tabs, terminals, or metal casings to prevent short circuits
    • UL-certified materials ensuring long-term electrical stability

      Electrode Tab Tapes

      • Flame-retardant and solvent-resistant
      • Provides precise wrapping for aluminum and nickel tabs
      • Strong heat resistance for ultrasonic and laser welding processes

        Cell Wrap and Module Protection Tapes

        • Pressure-sensitive adhesive (PSA) systems optimized for pouch, prismatic, and cylindrical formats
        • Provides abrasion and impact protection during assembly and transportation
        • Contributes to pack structural stability and insulation

          Masking and Process Tapes

          • Used for coating, slitting, and electrode cutting operations
          • Clean removal with minimal residue
          • Compatible with high temperature drying and solvent environments

            Applications Across the Battery Value Chain

            • Electrode Manufacturing: Masking, slitting, and fixation during coating and drying
            • Cell Assembly: Tab insulation, winding, stacking, and pouch sealing
            • Module & Pack Assembly: Busbar protection, cable bundling, and pack insulation
