Custom options are also available to suit your needs.

Less mess and better long term thermal performance

Thermal phase change materials are comparable to thermal grease, they melt and solidify as they absorb and release heat. These materials are excellent as they enable a much cleaner process compared to thermal grease. Watch the video for more details on the qualities and benefits of phase change materials.

What are phase change materials?

Phase change material products replace grease as the interface between power devices and heat sinks to provide effective thermal performance in components. LOCTITE® dispensable and printable phase change thermal compounds create a significantly thinner bondline and lower thermal resistance when compared to other formats.

The no-mess thixotropic characteristics keep phase change material products from flowing out of the interface, simplifying handling and providing a non-tacky material at room temperature.

LOCTITE® Bergquist® thermal interface material phase change products can be integrated into a fully automated process, giving customers fast and flexible processing for mass production and high throughput.

Why use Henkel phase change materials?

Henkel is a world-leading phase change material supplier. LOCTITE® Bergquist® dispensable and printable phase change thermal compounds give you better long-term thermal performance, with less mess.

Our phase change materials react faster to a change in temperature than greases and pastes, changing from a solid to a flowable material to efficiently release and absorb heat for better dissipation and stronger thermal performance.

Save time and money in your manufacturing processes when you choose phase change materials as an alternative to thermal grease.
