Thermally Conductive Electrical Insulation Materials

Flexible, heat-conductive adhesive materials

Safe cooling in high-voltage environments

Thermally conductive electrical insulation materials are designed for applications that combine intensive heat generation with the need for full electrical insulation. They are used in advanced energy systems, power supplies, converters, batteries, and power modules – wherever maximum component protection and efficient heat management are required.

Effective electrical insulation with high thermal conductivity

Safe and efficient heat management in high-voltage systems.

PI-based and Glass Fibre–based materials provide excellent electrical insulation between components while effectively transferring heat away from heat-generating elements. They are the perfect choice for high-power systems where safety and thermal performance are equally important.

Stability under high temperature and mechanical load

Consistent performance in demanding environments

With outstanding thermal and mechanical resistance, these materials retain their properties even in extreme operating conditions – including continuous operation at 150–200 °C. They perform reliably where other insulating materials fail.

Advantages

FAQ

Frequently Asked Questions

Is phase-change material solid or liquid?

At room temperature, it remains solid for easy handling and assembly. Once the activation temperature is reached, it softens into a semi-fluid state, conforming to surfaces and improving thermal transfer efficiency.

No. These materials are designed for single-use applications. After the phase change and stabilization, reusing them is not recommended to maintain optimal performance.

Typically around 55–60°C, depending on the formulation. The activation point can be adjusted to the application — higher temperatures for high-power components.

No. IPT™ phase-change materials are electrically insulating, making them safe for electronic applications requiring short-circuit protection.

Phase-change materials provide a cleaner application, no leakage, easier automated assembly, and consistent thermal performance — ideal for mass production or precision devices.
