3M™ Boron Nitride Cooling Fillers are engineered to help improve thermal conductivity in polymers while maintaining or improving electrical insulation. Their unique properties make these additives beneficial for many thermoplastic, elastomer, and thermoset resins used in a wide variety of electrical and electronic applications — including thermal interface materials (TIM), 5G, consumer electronics, and automotive applications.
3M™ Boron Nitride Cooling Fillers are versatile ceramic materials offering thermal conductivity, temperature stability, low loss factor, chemical resistance, high reflectivity, lightweighting, and electrical insulation. The structure of layered hexagonal plates provides outstanding lubricating properties and is non-abrasive to tooling. 3M Boron Nitride products are manufactured at fully dedicated, ISO 9001- and 14001-certified facilities. These manufacturing processes are optimized for quality, efficiency, and consistency — helping ensure reliable and repeatable product performance.
