6020 Transparent Insulation Polyester (PET) Mylar Film

6020 Transparent Insulation Polyester (PET) Mylar Film

The 6020 Transparent Electrical PET Film is a biaxially oriented polyethylene terephthalate (PET) film specifically designed for demanding electrical insulation applications. It combines excellent electrical properties, outstanding mechanical strength, and superior transparency, making it a fundamental yet high-performance insulating material. 

Features of 6020 Transparent Electrical Insulation Film:

• Excellent Electrical Insulation: Offers high dielectric strength, stable dielectric constant, and volume resistivity. It effectively isolates electrical current, prevents breakdown, and ensures the safe and reliable operation of electrical equipment.

• Outstanding Mechanical Properties: Thanks to the biaxial stretching process, the film exhibits high tensile strength, tear resistance, and good dimensional stability. It can withstand certain mechanical stresses during processing and use, resisting deformation or damage.

• High Transparency & Surface Flatness: The film is clear and transparent with a smooth, uniform surface. This facilitates observation and alignment during application and provides an ideal substrate for subsequent coating, laminating, or printing processes.

• Good Heat & Chemical Resistance: Maintains stable performance within a temperature range of -60°C to 120°C, with the ability to withstand higher temperatures for short periods. It shows good resistance to most solvents and chemicals, adapting to complex working environments.

Due to its comprehensive properties, the 6020 transparent insulation film plays an irreplaceable role in the field of electrical insulation. Its primary applications include:

1. Motor & Generator Insulation: Used as slot insulation, inter-phase insulation, and liner insulation to protect motor windings and isolate conductive components at different electrical potentials. It is a key material for enhancing motor reliability and lifespan.

2. Wire, Cable & Coil Wrapping: Used for wrapping wires, cables, and various electromagnetic coils to provide a uniform insulating layer, enhancing their electrical insulation rating and mechanical protection.

3. Transformer Insulation: Widely used in various types of transformers (oil-immersed, dry-type, etc.) for conductor insulation, inter-layer insulation, and component isolation, ensuring safe and efficient transformer operation.

4. Composite Materials & Laminates: Serves as a base film for producing various flexible composite insulating materials (e.g., composites with Nomex paper, mica tape) and laminates, providing the end product with insulation, strength, and structural support.
