6051 Electrical Polyimide Film

6051 Electrical Polyimide Film

Polymide Film 6051 Introduction

6051 polyimide film or polyimide film sheet is one of the electrical insulation film. It is synthesized by polymerizing PMDA and ODA in strong polar solvents through the process of forming film and imines treatment at high temperatures. This insulation product has excellent mechanical capability, favorable electric insulation at temperatures as low as -452F(-269c) and as high as +752F(+400c). It can be used in compound insulation material, adhesive tape, electric wire, and motor industry, etc.

Key Performance Advantages of 6051 PI Film

1. Unrivaled Dielectric Breakdown Limits:With an AC dielectric strength exceeding 130 kV/mm for core gauges, it provides maximum electrical shielding at a fraction of the thickness of traditional composite papers.

2. Extreme Thermal Endurance: Unlike regular polyester films, polyimide does not have a defined melting point. It maintains high mechanical modulus and prevents short-circuits even during sudden, catastrophic thermal overloads.

3. Outstanding Chemical & Radiation Resistance: Chemically inert to all common organic solvents, acids, and transformer mineral oils, while exhibiting high resistance to corona discharge and ionizing radiation.

Applications in High-Tech Electrical Fields

1. H-Class Motors & Traction Machinery: Acting as critical slot liners, phase-to-phase insulation, and magnet wire wrapping in high-speed rail motors and electric vehicles (EV).

2. Specialty Cables & Windings: Serving as core wrapping tape for high-temperature oil-well pumps, aircraft wiring, and fire-resistant cables.

3. Transformer & Reactor Core Barrier: Providing low-profile, high-voltage insulation in dry-type and traction transformers.

4. Pressure-Sensitive Tapes: Utilized as the base film for high-temperature silicone adhesive masking tapes (Kapton-type tapes).

Frequently Asked Questions

Q1: What is the continuous temperature rating for 6051 polyimide film?

A: 6051 electrical grade PI film is rated for long-term continuous operation between 180°C and 220°C. It retains its critical mechanical flexibility and dielectric strength at these high temperatures, whereas standard polyester films degrade quickly above 130°C.

Q2: What is the difference between 6051 polyimide film and standard polyester (PET) film?

A: PET film is rated for Class E (120°C) and melts around 250°C. 6051 polyimide film is rated for Class H (180°C+), does not melt, and possesses much higher mechanical tensile strength and chemical resistance, making it suitable for severe industrial environments.
