Thermal conductivity in polymer parts can be optimized to your application requirements, ranging from 1-15 W/mK
High electrical insulation
Suitable for many polymers like: thermoplastics, elastomers and thermoset resins
Very good processing properties and gentle on tooling: compounding, extrusion, injection molding
Used in a variety of electrical and electronic applications within consumer electronics and automotive markets
3M™ Boron Nitride Cooling Fillers are trusted across industries for effective temperature control. Downsized, lightweight and complex geometries require materials that can spread heat within a small space and transfer it to the surrounding air. Plastics are the material of choice, but they are usually not thermally conductive. Adding this product as a filler is an easy way to resolve this issue.
• LED lighting
• Consumer and automotive electronics
• High-capacity batteries
• Thermal interface materials
• High-performance adhesives
In the consumer electronics sector, 3M™ Boron Nitride Cooling Fillers aid in heat dissipation in mobile devices and televisions. As these devices get thinner, heat dissipation and electrical isolation are more crucial than ever. 3M™ Boron Nitride can be easily compounded with thermoplastics for injection molding or extrusion of pads, LED housings and heat sinks. One specific focus is in TIM applications – epoxy, silicon and acrylates – due to their thermal conductivity and electrical insulation capabilities, in addition to having a range of particle distributions and top cut sizes.
