3M™ Boron Nitride Cooling Fillers

Take thermal management to the next level, while maintaining electrical insulation.

  • Boron Nitride Heat Transfer

    Thanks to their enhanced thermal management capabilities, these materials are enabling a new generation of electrical and electronic components that offer improved performance, reliability and energy savings.

    3M™ Boron Nitride Cooling Fillers are a versatile family of ceramic fillers that improve the thermal conductivity of polymers while maintaining electrical insulation. Designed to meet the increasing need for “smart” polymers, these fillers can be formulated into many thermoplastics, elastomers, thermoset resins and adhesives. They help dissipate heat in consumer electronics and improve thermal management efficiency in high-capacity batteries, LEDs and automotive applications. By functionally integrating thermal management with electrical insulation, boron nitride-filled compounds may even enable lighter, simpler component designs – which can reduce total system costs.

    3M’s application engineering team has the experience and technical expertise to help customers optimize their formulations to take advantage of the unique properties of boron nitride cooling fillers.
