Exceptional Electrical Insulation Performance

This polyester film is specifically designed for electrical insulation, offering a high dielectric strength and a breakdown voltage of 2.2 KV. Its low shrinkage (<1% at 150C) and high elongation at break ensure it maintains integrity and effectiveness under thermal and mechanical stress.

Reliability in Moist and High-Temperature Environments

With low moisture absorption (0.4%) and water absorption (<0.8%), our polyester film is ideal for environments where humidity and heat are concerns. Its self-extinguishing capability adds a vital layer of safety, making it suitable for use in sensitive electrical and industrial settings.

Flexible, Durable, and User-Friendly Application

This transparent, single-layer film is supplied in convenient rolls for easy handling. Users benefit from its combination of smooth surface, high tensile strength, and straightforward installation guideline-apply only on clean, dry surfaces for optimal performance and adhesion.

FAQ's of Test Specifications:

Q: How should the polyester film be installed for best results?

A: For optimal insulation and adhesion, the film should be applied to clean, dry surfaces only. Follow the installation guideline to ensure strong bonding and effective electrical insulation.

Q: What are the primary benefits of using this polyester film for electrical insulation?

A: The main benefits include high dielectric strength, excellent tensile strength, a high breakdown voltage, low moisture and water absorption, self-extinguishing behavior, and reliable performance up to 150C.

Q: When is it ideal to use this material in electrical applications?

A: This polyester film is ideal when strong electrical insulation is required in environments with high humidity, elevated temperatures, or where fire safety is critical due to its self-extinguishing nature.

Q: Where can this insulation film be used within an installation?

A: It is suitable for use in transformers, electrical panels, motors, cable wrapping, and any other applications where insulation, transparency, and durability are essential.

Q: What is the expected shelf life, and how should it be stored?

A: The shelf life of the polyester film is 12 months when stored in a cool, dry place, as recommended. Proper storage preserves its insulating properties and handling characteristics.

Q: How does the film benefit from its moisture and water absorption properties?

A: With only 0.4% moisture absorption and less than 0.8% water absorption, the film resists swelling or degradation in damp conditions, ensuring consistent insulation over time.
