Polymer Melt-Blown Material

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.

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

  • Produced using Polyetherimide (PEI) resin, through slurry preparation, sheet forming, and drying-curing processes.
