We at Sui On Insulating have been closely working with Mylar® insulation sheet applications for decades, serving industries such as energy, data centers, automotive, and electrical transformers. Understanding the advantages and potential drawbacks of Mylar® insulation is essential for our clients, as it helps them make informed decisions for their high-voltage and high-performance equipment. In this article, we will share our insights on Mylar® insulation sheet, highlight our solutions, and introduce relevant products like Dupont Emperor Kaladex® .

Advantages of Mylar Insulation Sheet

One of the main reasons our clients choose Mylar® insulation is its excellent dielectric strength and thermal resistance. Mylar insulation sheet offers stable performance under various temperatures and electrical loads, which is particularly important in data center and power transformer applications. At Sui On Insulating, we provide Mylar® insulation sheet in multiple thicknesses and sizes, ensuring clients can source exactly what their designs require. Additionally, Mylar® insulation is lightweight and flexible, making it easier for installation in complex geometries without compromising performance. By combining our strong R&D capabilities and advanced production equipment, we ensure consistent quality that aligns with industrial standards.

Potential Drawbacks and Considerations

Despite its benefits, Mylar® insulation sheet does have some limitations that clients should be aware of. For example, its performance can be affected by prolonged exposure to high moisture levels or certain chemicals. At Sui On Insulating, we work closely with clients to provide recommendations on protective coatings and proper handling to mitigate these risks. Another consideration is cost: while Mylar® insulation provides high reliability, it can be more expensive than alternative films. However, our efficient production lines and vertical integration allow us to provide competitive delivery times without compromising quality, ensuring clients receive a reliable supply on schedule.

Kaladex® products are bi-oriented polyethylene naphthalene ester films that have been successfully developed and industrialized by DuPont Teijin.

The product has superior properties to PET film and is a high performance film with a good balance of excellent properties. Nowadays, it is widely used in high-density magnetic tapes, IC cards, FPC, capacitors, electrical insulation, and batteries.

Kaladex® polyethylene naphthalene ester film (PEN FILMS) has properties between polyester and polyimide films. It has excellent long-term aging resistance at high temperatures and can be used continuously at 155°C to meet Class F requirements. It has good dimensional stability at elevated temperatures, low heat shrinkage, better hardness, hydrolysis resistance and resistance to UV irradiation.

Conclusion: Making the Right Choice

In conclusion, selecting the appropriate Mylar® insulation sheet requires weighing its strengths and potential limitations. At Sui On Insulating, we guide our clients through this process by offering technical expertise, diverse product options, and reliable supply chains. While Mylar® insulation provides excellent dielectric and thermal performance, careful consideration of environmental exposure and cost is important. By leveraging products like Dupont Emperor Kaladex®  and our 40-year experience in insulation solutions, we ensure clients receive durable, high-quality materials that support their industrial applications.
