Insulation Materials for Litz Wire Manufacturing

At Metalitz, we are experts in selecting the ideal insulation materials for Litz wire manufacturing, ensuring optimal performance in high-frequency applications. Insulation material plays a key role in protecting the wire from environmental stressors, electrical interference, and temperature fluctuations. We carefully choose materials to meet stringent AWG standards where required. As a leading manufacturer, we tailor our solutions to meet specific thermal, electrical, and mechanical requirements, enhancing the durability of Litz wire.
In this guide, we will explore various types of inner and outer insulation materials used in Litz wire, providing detailed information on their temperature resistance, features, and applications across industries including automotive, aerospace, and power utilities.

Inner Insulation Materials for Litz Wire

1. Polyurethane Modified

Polyurethane insulation is known for its flexibility and self-soldering properties, making it a reliable choice for high-frequency inductors and RF transformers. It can withstand temperatures ranging from 155°C to 180°C, ensuring moisture resistance and long-term durability, especially in applications that require frequent soldering connections.

2. Polyester-Imide Modified

Polyester-Imide insulation is designed to provide enhanced electrical properties, making it suitable for motors, transformers, and other high-frequency power applications. It offers excellent dielectric strength and can resist temperatures up to 180°C, maintaining flexibility and thermal stability under varying load conditions.

3. Polyester-Imide Modified + Polyamide-Imide

This combination of Polyester-Imide and Polyamide-Imide insulation offers superior dielectric strength and can withstand higher temperatures of up to 200°C. It is highly durable in demanding applications such as EV chargers and high-frequency chokes, where resistance to heat and electrical stress is essential for performance.

4. Polyamide-Imide

Polyamide-Imide insulation is engineered for extreme environments, offering temperature resistance up to 220°C. This insulation provides superior mechanical strength and chemical resistance, making it ideal for high-stress applications such as medical devices and automotive systems. It ensures stability even under continuous exposure to high heat and stress.
Choosing the right insulation and Conductor material is critical for the optimal performance of Litz wire in high-frequency applications. Whether for aerospace, medical devices, automotive systems, or industrial applications. Metalitz offers a wide range of insulation options tailored to meet your specific needs.
