High Quality Polyester Laminates - Versatile Solutions

Polistrat and applications

Polistrat is Filmcutter's unique multilayer laminate, made by laminating together multiple polyester films. Lightweight, economical, space-saving and easy to handle, Polistrat is a new technology used as a physical and dielectric separation between the primary and secondary of resin transformers. Due to its extreme ease of use, the material is used directly by the customer to form cylinders that act as an insulation barrier between low and high voltage, all while ensuring Thermal Class F (155 °C).

Polistrat, Filmcutter's unique multilayer laminate, is the most viable alternative to the heavy fiberglass cylinders used in resin transformer insulation.

Polistrat can be supplied in rolls of variable heights up to 2,000 mm depending on the measures requested by customers. In addition to this main application, Polistrat can also be used in lower heights, starting from 35 mm, as a false coil.
Its ease of management, its practical application and its low cost make Polistrat the best product in the market for barrier insulation between high and low voltage in resin transformers.

Composition and Uses of Polyester Laminate

Polyester laminate is a versatile and reliable material that finds wide use in a variety of sectors and applications. This material is composed of thin sheets of polyester that are laminated together using a pressing and heating process. Thanks to its excellent insulating properties, it is widely used in the electrical industry for the production of insulation for transformers, electric motors, generators, and other electrical equipment. Its ability to withstand high temperatures and electrical stresses makes it an ideal choice for demanding operating environments.

One of the distinctive features of polyester laminate is its mechanical strength, which makes it particularly suitable for applications where high robustness and durability are required. This material can withstand mechanical stresses without compromising its insulating properties, ensuring reliable protection against short circuits and other emergency situations.

Additionally, it offers superior chemical resistance, making it suitable for applications in aggressive environments where a variety of corrosive chemicals are present. This corrosion resistance makes it a popular choice for industrial applications where a high degree of safety and long-term durability is required.

In addition to its insulating and mechanical properties, it also offers good dimensional stability, which is essential for applications where dimensional precision and consistency over time are required. This stability ensures that electrical components made with this material maintain their original dimensions and shapes even in adverse operating conditions.

Another significant advantage is its lightness and flexibility. These characteristics make it easy to work with and adaptable to a variety of configurations and designs, allowing greater flexibility in the engineering of electrical products. Additionally, its lightness makes it an ideal choice for applications where reducing the overall weight of components is necessary, such as in electric vehicles or aircraft.

Finally, polyester laminate is also an eco-friendly and sustainable material. It is recyclable and can be produced using low-impact environmental processes, reducing the overall environmental impact. This sustainability makes it a responsible choice for companies looking to reduce their environmental footprint and promote sustainable production practices.

In conclusion, polyester laminate is a versatile, reliable, and durable material that offers a unique combination of insulating, mechanical, chemical, and dimensional properties. Its wide range of applications and numerous advantages make it a preferred choice in the electrical industry and many other sectors. With its strength, flexibility, lightness, and sustainability, it continues to be a first-class insulation solution for the technological challenges of the present and future.
