Boron Nitride in Engineering Technical Polymers
Historically, the use of metal heat sinks has been the preferred option for dissipating heat from mechanical and electronic subassemblies. This led to the need to create complex systems and assemblies to electrically isolate the metal parts, increasing assembly costs and time, as well as degrading the heat dissipation properties of the system.
Thermally conductive polymers, which are inherently electrically insulating, represent an innovative alternative for this sector. The HeBoFill® COOL LINE range has been specifically designed for use in polymer development. These polymers take advantage of the unique properties of Boron Nitride, which include high thermal conductivity as well as electrical insulation. An additional advantage that can be obtained by incorporating HeBoFill® additives into the polymer substrate is the reduction of wear resulting from reduced friction. Such polymer compounds are, therefore, highly suitable for use in polymer bearings and other components in transmission systems.
As a result, both the performance and the range of applications for base polymers can be increased by using Boron Nitride HeBoFill®. Mechanical and electronic components can be directly assembled or encapsulated, making assembly easier and simplifying the system. It has been demonstrated that heat dissipation from the components, electrical insulation reliability, vibration protection, and resistance to dirt and moisture all significantly improve using these solutions.
In addition to its use as a solid lubricant and as a thermally conductive and electrically insulating additive, Hexagonal Boron Nitride is also successfully used as a nucleating agent in the production of bioplastics.
HeBoFill® Boron Nitride additives offer a wide range of products specifically designed for use in polymer engineering. Depending on the requirements, custom solutions are also available for the specific needs of each application.
HeBoFill® – Boron Nitride Powder for Polymer Engineering
Boron Nitride powder can be added to different base substrates to facilitate lubrication.
Because there is a wide variety of situations and processes where Boron Nitride powder – HeBoFill® can be applied, there are three product lines within the range:
- HeBoFill® Basic Line: An all-terrain line of Boron Nitride powder. It ensures easy implementation in production, providing good thermal and non-stick properties.
- HeBoFill® Lub Line: Improves lubrication due to its crystalline structure. Ideal for use in lubricants or greases.
- HeBoFill® Cool Line: The line to choose if you want to enhance the thermal conductivity of the base material without altering its electrical insulation properties. Especially aimed at sectors like electric cars or electronics due to their increasing thermal management needs.
