Thermal Resistance and Electrical Insulation: PP Insulating Flame Retardant Films vs. Polyimide (PI) Films

Introduction

Choosing the right insulating film for high-performance applications requires a detailed understanding of thermal resistance and electrical insulation properties. PP insulating flame retardant films and polyimide (PI) films are both used in industrial and electronic applications, but they differ significantly in performance. This article explores their advantages and limitations in terms of heat resistance and electrical insulation.

1. Thermal Resistance Comparison

  • PP Insulating Flame Retardant Films: Can withstand temperatures up to 150°C, making them suitable for medium-temperature applications.

  • PI Films: Exceptional thermal stability up to 400°C, ideal for aerospace, automotive, and high-performance electronics.

  • Degradation and Longevity: PI films offer superior heat resistance and durability compared to PP films.

2. Electrical Insulation Properties

  • Dielectric Strength: PP insulating films provide reliable insulation for general electrical applications.

  • High-Voltage Applications: PI films are preferred in applications requiring high dielectric strength and resistance to extreme environmental conditions.

  • Moisture Resistance: PI films exhibit better resistance to humidity and harsh conditions compared to PP films.

3. Application Suitability

  • PP Insulating Flame Retardant Films: Used in consumer electronics, electrical wiring, and moderate-temperature insulation.

  • PI Films: Found in aerospace, high-voltage applications, and demanding industrial environments.

  • Cost vs. Performance Trade-off: PP films are more economical, whereas PI films provide unmatched durability and high-performance insulation.

Conclusion

Both PP insulating flame retardant films and PI films serve essential roles in different industries. While PI films excel in extreme conditions with superior thermal resistance and dielectric properties, PP films offer a cost-effective solution for general insulation needs.
