PEI Isolation Paper
AF-3100

Polyetherimide insulating paper is a high-performance insulating material made through a melt-blown process. It has excellent electrical properties, heat resistance and excellent sealing properties. It has a blocking effect and is not easy to burn. It is widely used in electrical equipment in the fields of power, electronics, aerospace, etc. for insulation, protection and isolation.

PEI Isolation Paper | High-Performance Insulating Solution for Power, Electronics, and Aerospace Applications

Key Features

  • Excellent Insulation: Effectively isolates electric current, preventing leakage and short circuits, ensuring equipment safety.
  • High Temperature Resistance: Outstanding thermal stability allows continuous operation in high-temperature environments without degradation or deformation.
  • Superior Breathability: Good air permeability helps release trapped gases and moisture, reducing condensation and voids in insulation structures.
  • Flame Retardant: Non-flammable with flame-retardant performance, significantly improving electrical equipment safety.

Applications

  • Power Equipment: Widely used in transformers, motors, and generators for reliable insulation protection.
  • Electronic Products: Suitable for insulation structures in cables, circuit boards, and other electronics, enhancing safety and stability.

Test Results

  • Dk (10GHz): 2.74
  • Df (10GHz): 0.0025
  • Heat Resistance: ≥196℃ (continuous operation)
  • Flame Retardant Rating: UL 94 VTM-0, verified by the National Chung-Shan Institute of Science and Technology (NCSIST).

Manufacturing Process
